Question

A system consist of a car with momentum 25,0000 kg*m/s,traveling south, and a truck with momentum 100,000 kg*m/s,traveling north. They have a head on collision and stick together.Which statement correctly describes the system immediately afterthe colllision? a. The total mechanical energy of the dsystem is conveted tothermal energy b. Part of the kinetic energy of the system is converted tothermal energy c. The total kinetic energy of the system is converted tothermal energy d. The ttoal kinetic energy of the system is conserved e. The total mechanical energy of the system isconserved A system consist of a car with momentum 25,0000 kg*m/s,traveling south, and a truck with momentum 100,000 kg*m/s,traveling north.

Explanation / Answer

In the case of inelastic collision the part of the kineticenergy of the system is converted to thermal energy. So correct option is (b)
