A force of 186 N acts on a 7.0 kg bowling ball that was at rest. The bowling ball reaches a speed of 10.5 m/s. How much time was the force in contact with the ball?

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.

Ithink the answer is c but then again i'm probably wrong
