11. A motorcycle is moving at a velocity of 19.0 m/s before slamming on its brakes. The motorcycle comes to a complete stop (0 m/s). Assuming the acceleration of the
motorcycle's breaks were -7.60 m/s2, how much time did it take for the motorcycle to
stop?

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.

It maybe because uranus is made of gas but uranus has a solid core in the middle
