A motorcycle is traveling up one side of a hill and down the other side. The crest of the hill is a circular arc with a radius of 43.1 m. Determine the maximum speed that the cycle can have while moving over the crest without losing contact with the road.

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.
