Textbook Question
Chapter 2, Problem 54TAS
A rock band’s tour bus, mass M, is accelerating away from a stop sign at rate a when a piece of heavy metal, mass M/5, falls onto the top of the bus and remains there.
(a) Show that the bus’s acceleration is now a.
(b) If the initial acceleration of the bus is 1.2 m/s2, show that when the bus carries the heavy metal with it, the acceleration will be 1.0 m/s2.

A 925-kg pickup decelerates to rest from a speed of 75 km/h in a distance of 140 m. Consider that the pickup is initially moving in the positive direction.
Suppose instead of braking that the pickup hits a concrete abutment at frill speed and is brought to a stop in 2.00 m. Calculate the force, in newtons, exerted on the pickup in this case.
Baby Kellyn was bouncing up and down in a "bouncy chair" which hangs from a chain that is attached to a spring. At one
particular time, after jumping in the air, Kellyn and the chair were moving downward with a speed of 1.7 m/s while speeding
up at a rate of 3.3 m/s?. Kellyn has a mass of 4.8 kg and the chair has a mass of 1.2 kg. Calculate the force (in units of
newtons) that the chain exerted on the chair at this time. Consider a positive force to point up and a negative force to point
down. The sign, positive or negative, of your answer is important.
What force is necessary in order to change the velocity of a 2.00 kg object from
-4.00 m/s to +3.00 m/s in 0.10 seconds?
