Kinetic energy is dependent only on the mass and the velocity of the object.
Neglecting air resistance, Sammy Smarts on a high ladder releases a ball that strikes the ground with 100 J of kinetic energy. If he were to instead throw the ball straight upward, it will soon reach the ground with a kinetic energy of
A. less than 100 J.
B. 100 J.
C. more than 100 J.
