Vi = 8 ft/s 3 ft The girl throws the ball with a horizontal velocity of v, = 8 ft/s. If the coefficient of restitution between the ball and the ground is e = 0.8. determine the velocity of the ball just after it rebounds from the ground and the maximum height to which the ball rises after the first bounce.

6. For this series of 4 questions, a 1-1b ball is dropped from rest and falls a distance before striking the smooth plane at A. It bounces from the plane, and then strikes the plane again. You will be asked to solve for different things. Please pay attention: the numbers may change from problem to problem since they are randomized. 2) If the ball is dropped form rest at a height h = 4.5 ft, and the coefficient of restitution...

While scrambling directly toward the sideline at a speed v_Q = 24 ft/sec, the football quarterback Q throws a pass toward the stationary receiver R. At what angle a should the quarterback release the ball? The speed of the ball relative to the quarterback is 51 ft/sec. Treat the problem as two-dimensional.

2/13 A ball is thrown vertically upward with an initial speed of 80 ft/sec from the base A of a 50-ft cliff. Determine the distance h by which the ball clears the top of the cliff and the time t after release for the ball to land at B. Also, calculate the impact velocity UB. Neglect air resistance and the small horizontal motion of the ball. 50 Uo Problem 2/13

Water is ejected from the water nozzle with a speed
v0 = 41.4 ft/sec. For what value of the angle
θ will the water land closest to the wall after clearing
the top? Neglect the effects of wall thickness and air resistance.

Starting from rest, a child throws a ball with an initial speed v at B degrees above the horizontal. The child then chases after the ball, accelerating at a constant acceleration a. If the child wants to catch the ball at the same height it was thrown, what must be the child's acceleration a? Use g for the gravitational constant.
