A tennis ball is shot straight up from the ground. After traveling 4.00 m, the ball passes a 4.00 m high window and then continues straight up until it loses all its upward velocity and falls to the ground. During the last second of its flight before it hits the ground, the ball drops 20.0 m.
a) What is the maximum height above the ground reached by the ball?
b) What is the total time for the ball’s flight?
c) When the ball is travelling upward, during what time interval is the ball passing the window?

A tennis ball is hit straight up at 24.0 m/s from the edge of a sheer cliff. Sometime later, the ball passes the original height from which it was hit. Use the value of g-10.0m/s 1. How fast is the ball moving at that time? 2. If the cliff is 32.0 m high, how long will it take the ball to reach the ground level? 3. What total distance did the ball travel? Set-up: Draw diagram.

A ball is shot from the ground into the air. At a height of 9.80 m, its velocity is v = (8.50i + 4.00j) m/s, with i horizontal and j upward. To what maximum height does the ball rise? What total horizontal distance does the ball travel? What is the magnitude of the ball's velocity just before it hits the ground? What is the angle (below the horizontal) of the ball's velocity just before it hits the ground?

Carlon launched a toy rocket vertically up from ground level (y = 0 m), at time t = 0.0 s. The rocket engine provides constant upward acceleration of 12.3 m/s2 during the burn phase. At the instant of engine burnout the rocket has risen to 89 m. The rocket continues to rise in unpowered flight, reaches maximum height, and falls back to the ground. The maximum height reached by the rocket is closest to:

A lacrosse ball is hurled straight up, leaving the head of the stick at a height of 2.00 m above the ground level. The ball passes by a 1.25-m-high window in a time of 0.350 s as it heads upward. 1) Calculate the initial speed of the ball if it is 13.0 m from the ground to the bottom of the window. Ignore the effects of air resistance. (Express your answer to three significant figures.) m Submit
