Chapter 9, Problem 80P
A 200-g block is released from rest at a height of 25 cm on a frictionless 30° incline. It slides down the incline and then along a frictionless surface until it collides elastically with an 800-g block at rest 1.4 m from the bottom of the incline (Fig. 9.29). How much later do the two blocks collide again?

1. You want to drive cart A, initially at rest, through a
piece of paper by launching cart B against it. Both carts
have the same mass, and you've determined that the larger
the kinetic energy of an object, the more easily it goes
through a piece of paper. One side of cart B is equipped
with velcro pads so that it sticks to cart A; the other side
is smooth and collides elastically. Which side of cart B do
you use? Explain briefly.

A spring of force constant k is attached to the back end of the second glider.
