1. In a scene in an action movie, a man is being chased across a roof top. To escape, he runs off the edge of the building and falls to

the roof of a nearby shorter building. The tall building is 50 m high, the short building is 40 m high and there is a 5 m gap in-between the buildings. a) What is the minimum velocity he must be running at to safely land on the shorter building? b) If the man ran at this minimum velocity, what would his velocity be when he lands on the shorter building?
