Two identical balls are thrown from the top of a cliff, each with the same speed. One is thrown straight up, the other straight down. How do the kinetic energies and speeds of the balls compare as they strike the ground? A) The ball that is thrown straight up will have more kinetic energy but less speed than the ball that is thrown straight down.

B) The ball that is thrown straight up will have more kinetic energy and more speed than the ball that is thrown straight down.
Both balls will have the same kinetic energy and speed.

C) The ball that is thrown straight up will have more kinetic energy but less speed than the ball that is thrown straight down.

D) The ball that is thrown straight down will have more kinetic energy and more speed than the ball that is thrown straight up.
