Question

A ball is thrown at 60° with initial velocity of 10 m/s, it reaches the maximum height and on return it hit an
inclined surface 2 m above the initial level and inclined at 40° and bounces back at 90° with the inclined
surface, with half of the speed of impact. What is the horizontal distance of the ball from A to B?

A baseball pitcher throws a pitch with an initial velocity of 45 m/s (100 mph!), directed horizontally. You will be asked to find how far the ball drops vertically by the time it crosses the plate 18.0 m away. Find the time it takes for the ball to travel the horizontal distance to the plate. 2.5 s 0.40 s 4.6 s 0.22 s
A ball is thrown vertically upward with an initial speed of 88 ft/sec from the base A of a cliff with H = 60 ft. 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 magnitude of the impact velocity vg. Neglect air resistance and the small horizontal motion of the ball. Answers: h = i ft t = i sec VB = i ft/sec
