## Document Summary

The ball is in contact with the wall 0. 05 s. what is the avergage force exerted on the wall by the ball. 3000n: a person stands on the edge of a cliff. She throws three identical rocks with the same speed. Rock x is thrown vertically upward, rock y is thrown horizntally, and rock z is thrown vertically downward. The force would be the same in both cases. Catch the ball they all hit the ground with the same speed. stationary: in the figure, determine the character of the collision. The masses of the blocks, and the velocities before and after are given. Complete inelastic the magnitude of the change of velocity the 5 kg ball experiences is greater then that of the 10kg ball: a 5kg ball collides head on with a 10 kg ball, which is initially stationary. The force would be the same in both cases they all hit the ground with the same speed.
