d The horizontal motion will carry the particle to the opposite wall, so d = vx tf and 7.6 m/s 18.4 m tf = d vx (18.4 m) = (7.6 m/s) = 2.42105 s .
a) What will be its speed when it hits the opposing wall? Correct answer: 9.86832 m/s (tolerance 1 %). Explanation:
is the time for the particle to reach the opposite wall. Horizontally, the particle reaches the maximum parallel distance when it hits the oppod , so the final site wall at the time of t = vx parallel velocity vy is vy = a t ad = vx (2.6 m/s2 ) (18.4 m) = (7.6 m/s) = 6.29474 m/s . The velocities act at right angles to each other, so the resultant velocity is vf = =

The answer is then "vQ < vP = vR ". Question 5, chap 4, sect 4. part 1 of 1 10 points A target lies flat on the ground 5 m from the side of a building that is 10 m tall, as shown below. The acceleration of gravity is 10 m/s2 . Air resistance is negligible. A student rolls a 5 kg ball off the horizontal roof of the building in the direction of the target. v m = 5 kg , not required h = 10 m , x = 5 m , and g = 10 m/s2 .

A baseball is thrown at an angle of 26 relative to the ground at a speed of 29.7 m/s. The ball is caught 70.9 m from the thrower. The acceleration of gravity is 9.81 m/s2 . a) How long is it in the air? Correct answer: 2.65436 s (tolerance 1 %). Explanation: Basic Concept: Horizontally, x = vx t = vi (cos )t Given:
Using Eqs. 1 and 2 and solving for vx , we have vx = = g x 2y -9.81 m/s2 (0.97 m) 2(-1.2 m)

That is, at what angle (in the range -90 to +90 relative to the horizontal directed away from the table) did the ball hit the floor? Correct answer: -67.9931 (tolerance 1 %). Explanation: The vertical velocity component with which the mug hits the floor is vy = vy0 + ay t = 0-gt = -(9.81 m/s2 ) (0.494619 s) = -4.85222 m/s . Hence, the angle at which the mug strikes the floor is given by = tan-1 vy vx -4.85222 m/s = tan-1 1.9611 m/s = -67.9931 . R= Solution:

Question 13, chap 4, sect 4. part 2 of 3 10 points (1) (2) (3) How long does it take the projectile to hit the ground? Correct answer: 2.64026 s (tolerance 1 %). Explanation: From Eq. 3, the time t2 for the projectile to decend from the top to where the projectile hits the ground is 2 [y + yi ] g
v = vi sin - g t , 2 vy y = i , and 2g 1 y = vyi - g t . 2 Let : vi xi yi = 12 m/s , = 0 m, = 7 m , and = 59 .
t2 = =
Solution: For the horizontal and vertical components of vector of vi , we have vxi = vi cos = 6.18046 m/s , vyi = vi sin = 10.286 m/s . and
2 [(5.39806 m) + (7 m)] (9.8 m/s2 ) = 1.59067 s .
Or symbolically, we have

Using Eq. 1 (|vyi | = g t), the time t1 to reach the maximum height, (i.e., vtop = 0 , the velocity the at top) is vy t1 = i g (10.286 m/s) = (9.8 m/s2 ) = 1.04959 s .

There are (9.5 m - 0.5 m) 1 interval 1m =9
time intervals between the two end points. Basic Concept: x = x0 + vx t . (1)

rest down the incline with a constant acceleration of 6.06 m/s2 and travels 25.5 m to the edge of the cliff. The cliff is 23.7 m above the ocean. The acceleration of gravity is 9.8 m/s2 . Find the car's position relative to the base of the cliff when the car lands in the ocean. Correct answer: 33.0067 m (tolerance 1 %). Explanation: Given : a = 6.06 m/s2 , l = 25.5 m , h = 23.7 m , and = 10.1 . The speed of the car when it reaches the edge of the cliff is given by
2 v 2 = vi + 2 a l = 2 a l
Solution: The vertical height covered and time lapse from the first data point to the maximum vertical height is ymax = ymax - ymin = (75 m) - (5 m) = 70 m , and xmax - xlef t tmax = vx (5 m) - (0.5 m) = (1.16279 m/s) = 3.87 s . Using Eq. 2 and solving for g, we have 2 ymax g= (t)2 2 (70 m) = (3.87 s)2 = 9.34773 m/s2 . Note: The equation for the trajectory of the projectile, as plotted in the figure, is y = ymax - ymax x - xmax (xmax - xlef t )2

Consider the following statements: Ball A has greater launch speed than ball B. Ball B has greater launch speed than ball A. Ball A and ball B have the same launch speed. Ball A spends more time in the air that ball B. Ball B spends more time in the air that ball A. Ball A and ball B spend the same time in the air. Which of the statements are correct? 1. and 2. and 3. and 4. and 5. and 6. and correct 7. and 8. and 9. and Explanation: Basic Concept: The time of flight in all cases depends only on the vertical component of the initial velocity. The launch speed depends on both the vertical component and horizontal component of 2 2 the initial velocity: v = vx + vy . Solution: In this case ball A has a greater maximum height than ball B so its vertical component of the initial velocity is greater. For a fixed launch speed, a trajectory has its maximum range when projected with a launch angle of 45 , so ball B has the least possible initial velocity for the given range R. Therefore, ball A has greater launch speed than ball B and ball A spends more time in

Explanation: In this case the balls have the same maximum heights, so the time of flight is the same for both. Since ball A has a shorter range, the horizontal component of its initial velocity must be less than that of ball B. Therefore, ball B has greater launch speed than ball A and ball A and ball B spend the same time in the air. See Paul Hewitt's books for more examples of "Figuring Physics". Question 21, chap 4, sect 4. part 1 of 1 10 points A daredevil decides to jump a canyon of width 15.7 m. To do so, he drives a motorcycle up an incline sloped at an angle of 17.4 . The acceleration of gravity is 9.8 m/s2 . What minimum speed must he have in order to clear the canyon? Correct answer: 16.4193 m/s (tolerance 1 %). Explanation: The time to reach the opposite bank is found from x = v0x t . as t= x v0x (15.7 m) . = v0 cos 17.4
Consider the following statements: Ball A has greater launch speed than ball B. Ball B has greater launch speed than ball A. Ball A and ball B have the same launch speed.

By how many degrees will she be blown off course? Correct answer: 14.7436 (tolerance 1 %). Explanation: The eagle's velocity is directed due south, with the wind directed toward the west. The two velocities form a right triangle with vwind the side opposite the angle , and veagle the side adjacent, so tan = = arctan vwind 1.5 m/s = veagle 5.7 m/s 1.5 m/s 5.7 m/s = 14.7436
A river flows with a uniform velocity v. A person in a motorboat travels 1.57 km upstream, at which time a log is seen floating by. The person continues to travel upstream for 69.7 min at the same speed and then returns downstream to the starting point, where the same log is seen again. Find the flow velocity of the river. Assume the speed of the boat with respect to the water is constant throughout the entire trip. (Hint: The time of travel of the boat after it meets the log equals the time of travel of the log.) Correct answer: 0.187709 m/s (tolerance 1 %). Explanation: Let u be the boat's speed in still water and let be the distance traveled upstream in t = 69.7 min and T be the time of return. Then, for the log, d = v (t + T ) , and for the boat, = (u - v) t + d = (u + v) T . Combining the above gives +d d = + . v u-v u+v Substituting = (u - v) t from the equation above yields the equation for v (u - v) t + d d =t+ . v u+v
Question 23, chap 4, sect 6. part 2 of 2 10 points How fast will she be moving relative to the ground? Correct answer: 5.89406 m/s (tolerance 1 %). Explanation: The resultant velocity is the hypotenuse of the right triangle, so you can use the Pythagorean theorem v=
2 2 vwind + veagle
homework 03 VENNES, ROSS Due: Sep 21 2007, 1:00 am Simplifying this equation, we obtain v= d 2t 1570 m = (2) (4182 s ) = 0.187709 m/s .
13
Digression: The answer can be readily understood in the following way. Imagine you are at rest on the log observing the motion of the boat. You need to convince yourself that, since both you and the boat are affected in the same way by the water flow, the motion of the boat relative to you is independent of the water flow. In other words, if the boat is moving away from you with a speed say u, for a time t, it will be moving back toward you with the same speed as you see it. So the time interval for the entire trip, i.e. moving away from you and coming back to you is 2t. During this time, the distance which the log has d drifted is d. So the drift-speed of the log is 2t .
