A 1710 kg truck traveling at 10.1 m/s west smashes into a car moving at 15.5 m/s west. After the collision, the truck is traveling at 3.55 m/s west and the car is traveling at 22.6 m/s west. What is the mass of the car?

1) when you rub your hands together quickly, the kinetic energy is converted to mechanical energy.2) thermal energy from the sun travels to earth as infrared waves.3) energy is transferred through the matter of space by electromagnetic waves. 4) when a match is burned, chemical potential energy is converted to thermal and radiant energy. 5) seismicwaves are caused by back and forth movement , or vibration, of an object. 6) mechanicalenergy in an engine changes thermal energy into kinetic energy to make a car move.

Sorry i don’t know what to do
