23. imagine a ball on a track where no energy is transferred between the ball and the track
or between the ball and the air around it. the ball starts from rest at the position labeled b
and moves along the track toward positions d, e, f, and g. place a dot on the highest
position the ball will reach before stopping and going back down the track. explain why the
ball stop at that position? (remember that no energy is transferred between the ball and the
track or between the ball and the air around it.)
