Question1

Assume that the ball's initial velocity was 45 above the horizontal, and ignoring air resistance, what did an initial speed of the ball want to be to produce such a home run if the ball was hit at a point 0.7 (2.3 ) above ground level? Imagine that the ground was completely flat.

Question2

A car drives horizontally off a 71 -high cliff at a speed of 29. Ignore air resistance.

a) How long will it take the car to hit the ground?

b) How far from the base of the cliff will the car hit?
