5. Johnny lets a 0.5kg ball roll on the floor of the classroom. The ball gradually slows down. The coefficient of friction between the floor and the ball is 0.18. Draw a free body diagram and calculate the acceleration of the ball.​

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.

A) acceleration. this seems to be the one that makes sense.
