The rectangular plate shown weighs 75 lb and is held in position shown by hinges A and B. Rather than being held by cable EF as shown, assume cable EF has been replaced by a cable attached to points E and H. Assuming that the

A 1 kg mass moving at 3 m/s has a head on collision with a 2 kg mass at rest. After the collision, the 1 kg mass is moving in its original direction with a speed of 2 m/s. Match the following:

Do all forces change kinetic energy? From a *conceptual*

A 1 kg mass traveling at 2 m/s collides head on with a 3 kg mass traveling at 4 m/s. What is the magnitude of the final momentum (in kg m/s) of the 3 kg mass if the one kg mass rebounds in the opposite
