Question

As a movie stunt coordinator, you need to be sure a stunt will be safe before it is performed. If a stunt- woman is to run horizontally off the roof of a three-story building and land on a foam pad 7.35 m away from the base of the building, how fast should she run as she leaves the roof? (Each story is 4.00 m.)

Answer 1

h = ½ g t² ... t = √(2 * 12.0 / g)

v = d / t = 7.35 m / t
