Textbook Question
Chapter 2, Problem 73EAP
Your goal in laboratory is to launch a ball of mass m straight up so that it reaches exactly height h above the top of the launching tube. You and your lab partners will earn fewer points if the ball goes too high or too low. The launch tube uses compressed air to accelerate the ball over a distance d, and you have a table of data telling you how to set the air compressor to achieve a desired acceleration. Find an expression for the acceleration that will earn you maximum points.

In 1992, a 14-kg meteorite struck a car in Peekskill, NY, leaving a 20-cm-deep dent in the trunk.
If the meteorite was moving at 500 m/s before striking the car, what was the magnitude of its acceleration while stopping?
Find the time it takes for the meteorite to come to a complete stop.
A 7500-kg rocket blasts off vertically from the launch pad with a constant upward acceleration of 2.25 m>s 2 and feels no appreciable air resistance. When it has reached a height of 525 m, its engines suddenly fail; the only force acting on it is now gravity. (a) What is the maximum height this rocket will reach above the launch pad? (b) How much time will elapse after engine failure before the rocket comes crashing down to the launch pad, and how fast will it be moving just before it crashes? (c) Sketch ay@t, vy@t, and y-t graphs of the rocket’s motion from the instant of blast-off to the instant just before it strikes the launch pad
ANSWER ABC
A rescue helicopter is hovering over a person whose sailboat has capsized. One of the rescuers tosses a life preserver straight down to the person with an initial speed of 1.25 m/s and observes that it takes 1.75 s to reach the water. How high above the water was the preserver released? Note that the downdraft of the helicopter reduces the effect of air resistance on the falling life preserver, so that an acceleration equal to that due to gravity is reasonable.
