The script for an action movie calls for a small race car (of mass 1500 kg and length 3.0 m) to accelerate along a flattop boat (of mass 4000 kg and length 14 m), from one end of the boat to the other, where the car will then jump the gap between the boat and a somewhat lower dock. 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. Determine what the width of the gap will be just as the car is about to make the jump.

The script for an action movie calls for a small race car (of
mass 1500 kg and length 3.0 m) to accelerate along a flattop boat
(of mass 4000 kg and length 14 m), from one end of the boat to the

the gap between the boat and a
somewhat lower dock. 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.
Determine what the width of the gap will be just as the car is
about to make the jump.
