- 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.arrow_forwardHere we will look at an example of subatomic elastic collisions. High-speed neutrons are produced in a nuclear reactor during nuclear fission processes. Before a neutron can trigger additional fissions, it has to be slowed down by collisions with nuclei of a material called the moderator.

The masses of nuclei and subatomic particles are measured in units called atomic mass units, abbreviated uu, where 1u=1.66×10−27kg1u=1.66×10−27kg. Suppose a neutron (mass 1.0 u) traveling at 2.6×107m/s2.6×107m/s makes an elastic head-on collision with a carbon nucleus (mass 12 u) that is initially at rest.
