Chapter 9, Problem 107GP
In a physics lab, a cube slides down a frictionless incline as shown in Fig. 9–57 and elastically strikes another cube at the bottom that is only one-half its mass. If the incline is 35 cm high and the table is 95 cm off the floor, where does each cube land? [Hint: Both leave the incline moving horizontally.]

A bowling ball hangs from a 1.0-m-long cord, Fig. 7–30:
(i) A 200-gram putty ball moving 5.0 m/s hits the bowling
ball and sticks to it, causing the bowling ball to swing up;
(ii) a 200-gram rubber ball moving 5.0 m/s hits the bowling
ball and bounces straight back at nearly 5.0 m/s, causing the
bowling ball to swing up. Describe what happens.
(a) The bowling ball swings up by the same amount in
both (i) and (ii).
(b) The ball swings up farther in (i) than in (ii).
(c) The ball swings up farther in (ii) than in (i).
(d) Not enough information is given; we need the contact
time between the rubber ball and the bowling ball.

You are the technical advisor for the movie. The boat will initially touch the dock, as in Fig. 9-81; the boat can slide through the water without significant resistance; both the car and the boat can be approximated as uniform in their mass distribution.
