Kinematics - 1 v 1.0 ©2009 by Goodman & Zavorotniy Kinematics Chapter Questions 1.When you drive a car and take a quick look on the speedometer, what do you see velocity or speed? 2. A ball is thrown vertically up and is caught at the starting point; compare the traveled distance and displacement of the ball. 3.Can an object with a constant acceleration reverse it direction of travel? Explain. 4.Can an object have a varying velocity when its speed is constant? Explain. 5.Is it possible for an object to have average velocity equal to its instantaneous velocity? 6.What quantity describes how quickly you change your speed? 7.Can an object have a southward velocity and a northward acceleration? 8.Is it possible for an object to have average speed equal to the magnitude of its average velocity? 9.If the speedometer of a car reads constant speed 50 mi/h, does it mean that the car has constant velocity? 10.What does the area under the curve on a velocity-versus-time graph represent? 11.What does the slope of the curve on a displacement-versus-time graph represent? 12.What does the slope of the curve on a velocity-versus-time-time graph represent?
1.A rabbit can cover a distance of 80 m in 5 s. What is the speed of the rabbit? 2. During the first 50 s a truck traveled at constant speed of 25 m/s. Find the distance that it traveled. 3.An elevator ascends at a constant speed of 4 m/s, how much time is required for the elevator in order to travel 120 m upwards? 4.A racing car can complete a 900 m long lap in 15 s. What is the speed of the car? 5.It is known that a shark can travel at a speed of 15 m/s. How far can a shark go in 10 seconds? 6.How long does it take an airplane to fly 1500 miles if it maintains a speed of 600 miles per hour? 7.A person can run 280 m in 68 s. At what speed are they running? 8.How far does a runner travel if they maintain a speed of 8.5 m/s for 240 s? 9. A sportsman can develop a maximum speed of 12 m/s when he is swimming in a pool. Calculate the time interval that is required to travel a distance of 25 m. 10.A polar bear walks a distance of 160 meters in 60 seconds. What was its speed? 11.A train travels 120 seconds at a speed of 50 m/s. How far did it go? 12.How long will it take a runner to travel a distance of 1000 m at a speed of 12 m/s?

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
