A 1220 kg mass car traveling at a velocity of 22 m/s crashes into a 1475 kg parked car. After the crash, the parked car moves with a velocity 10 m/s. Calculate the first car's velocity after the crash.

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.
