Jen drops a ball with a mass of 0.100 kg from a height of 20.0 m The initial downward velocity of the ball is 5.00 m/s. What is the kinetic energy of the ball after it has fallen 10.0 m?
the k.e. is equal to the initial k.e. plus the potential energy from the drop
k.e. = (.5 * .100 * 5.00^2) + (.100 * g * 10.0)
g is gravitational acceleration
