(a) Compute the change in energy involved in walking (m = 90. kg) to the top of a 1200. meter high peak. (b) Use the conservation of total mechanical energy to compute the final velocity of an object dropped from that height just before it strikes the ground.

If a spring is displaced by 20cm from its equalibrium point by 200N, how much will it be displaced by a 400N force?

If a spring stretches to 2 cm when a force of 50 N is applied, find out its spring constant.
