12. A stone is dropped from the top of a cliff. It is seen to hit the ground below
after 3.55 s. How high is the cliff?
13. A ball is dropped from rest at the top of a building that is 320 m tall. Assuming

Instead it reverses direction and ends down on the ground below the window. Since the brick didn't break the glass, we know: О The force of the brick on the glass > the force of the glass on the brick. О The force of the brick on the glass the force of the glass on the brick. = О The force of the brick on the glass < the force of the glass on the brick.
