Chapter 3, Problem 23P

A bullet is fired upward with a speed v0 from the edge of a cliff of height h (Fig. P3.22). (a) What is the speed of the bullet when it passes by the cliff on its way down? (b) What is the speed of the bullet just before it strikes the ground? (c) If the bullet is instead fired downward with the same initial speed v0, what is its speed just before it strikes the ground? Express your answers in terms of v0, h, and g. Ignore air drag. Assume the bullet is fired straight up in (a) and (b) and straight down in (c).

A ball is thrown upward with a speed of 35 m/s from the edge of a cliff of height h = 15 m (similar to Fig. P3.22). (a) What is the speed of the ball when it passes by the cliff on its way down to the ground? (b) What is the speed of the ball when it hits the ground? Ignore air drag. Assume the ball is thrown straight up.

A basketball player standing under the hoop fires the ball straight up with an initial velocity of v0=4.5 m/s from 2.5 m above the ground. Part a) What is the maximum height, h(in meters), above the launch point the basketball will achieve? Part b) On his first attempt, the ball doesn't make it high enough to reach the hoop. If the hoop is at 3.5 m above the ground, what is the minimum velocity (in m/s) with which he mush launch his second attempt to reach the hoop?
An attacker at the base of a castle wall 3.60 m high throws a rock straight up with speed 8.20 m/s at a height of 1.50 m above the ground.   (a) If so, what is the rock's speed at the top? If not, what initial speed must the rock have to reach the top? m/s(b) Find the change in the speed of a rock thrown straight down from the top of the wall at an initial speed of 8.20 m/s and moving between the same two points. m/s(c) Does the change in speed of the downward-moving rock agree with the magnitude of the speed change of the rock moving upwards between the same elevations? Explain physically why or why not.
