A car drives straight off the edge of a cliff that is 58 m high. The police at the scene of the accident note that the point of impact is 126 m from the base of the cliff. How fast was the car traveling when it went over the cliff?

Answer 1

Calculate the time that it takes to fall 58 m. It will not depend upon the car's velocity, just the cliff height.

Divide 126 m by the time it takes to fall to the base of the cliff.

That wll be the car's velocity when it leaves the cliff. That velocity remains the horizontal component of V as it falls.
