An 80kg man falls our of a 1.5m tree starting at 0 speed. How much potential energy does he start with in the tree? When he hits the ground he loses all potential energy. Where did hid inital energy go? He travels while in contact with the ground .5cm. Calculate the amt of force the ground will excert on him in this scenerio. If he were to bend his kones his body travels downward .6m while his feet are in contact with the ground. Calculate the grounds force now converted to pounds.
