Unformatted text preview: from the edge of the barn does the snowball strike the ground? _____________________ υ 0 50˚ A R 35 m H O A x 90º υ 30° 15 m 3. A projectile is launched with α = 50˚ and it lands at point A as shown. The maximum height of the projectile at the peak of its trajectory is H = 80 m. (a) Find the total time of flight to the landing point A . _____________________ (b) Find the range of motion R (horizontal distance) of the projectile. _____________________ 4. A small bead moves on a circular hoop of radius R = 2 m in the counterclockwise direction as shown. If the speed of the bead at point A (the lowest point on the path) is 1.2 m/s and it is slowing down at a rate of 0.54 m/s 2 , find the magnitude and direction of the acceleration of the bead at A . a = _____________________ β (measured from + xaxis) = ________________________...
