The distance travelled can also be worked out by multiplying the speed by the time.If we combine these equations we can work out the time for travelling a set distance with a constant acceleration.

From the time, we can work out the final velocity. If the initial velocity is zero - which it is when he jumps off the top - then his final speed will be acceleration x time.

This is the fastest speed he could possibly reach and in reality will be a little slower due to air resistance. As the velocity of a falling body increases, so does its momentum. Momentum is a physics term; it refers to the quantity of motion that an object has.

Momentum is calculated by taking the mass of a body and multiplying that number by its velocity.
