Abullet of mass 0.02070 �� collides inelastically with a wooden block of mass 28.00 ��, initially at rest. after the collision the, system has speed of 1.180 �/�. (a) what was initial speed of the bullet? (b) what fraction of energy was transformed to other forms of energy?

B my friend lemme tell ya

So what is the question

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.
