A bullet is fired into a large stationary absorber and comes to rest. Temperature measurement of the absorber show that the bullet lost 1960 J of kinetic energy and high speed photos of the bullet show that ir was moving at 965 m/s just as it struck the absorber. What is the mass of the bullet?

4.21 grams with working on photo

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.
