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
no air resistance, what is the speed of the ball just before it strikes the ground?
14. Estimate (a) how long it took King Kong to fall straight down from the top

X = V₁t + Xo
For Constant Acceleration:
Vr = V + at
X = Xo+Vot +
v=V+2a(X-Xo)

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. О The brick didn't slow down as it broke the glass.arrow_forwardAlexandra (wearing rubber boots for traction) is attempting to drag her 32.6-kg Golden Retriever across the smooth ice by applying a horizontal force.
