Please help me with this question: 1. Bob a man with a mass of 90kg, climbs up a 3.5m high tree. a.) How much work must Bob do in order to make it to the top of the tree, assuming that he begins and ends at rest? Bob now jumps out of the tree and land on the ground. b.) How fast will he be going just before he hits the ground? c.) First assume that he forgets to bend his knees. That means that he wil land hard - the cushions on his feet will make him move downward 1.6cm while coming to a stop, but that's it. How much force will he feel from the ground while he stops? d.) As you can see, that enormous force result in a everely injured Bob. So rewind, and let's assum Bob bends his knees this time. That means that the ground forced is in contact with him while he moves 0.45cm downward. Now how much force will the ground exert on Bob?
