Adiver can change his rotational inertia by drawing his arms andlegs close to his body in the tuck position. after he leaves thediving board in the straight position (with some unknown angularvelocity), he pulls himself into a ball as closely as possible (thetuck position) and makes 2.00 complete rotations in 1.33 s. if hisrotational inertia decreases by a factor of 3.00 when he goes from the straight to the tuck position, what was his angularvelocity when he left the diving board?

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.
