Problem
A diver of mass 60 kg stands at rest on a platform 10 m above the water and then jumps. At a point 4 m above the water her speed is 8 m/s. Take g=10m/s2.
(i) Which form of energy (kinetic or potential) is greater when she is on the platform?
(ii) Which form of energy is greater when she is 4 m above the water?
(iii) Has her total mechanical energy increased, decreased or remained the same during the fall? State one reason for your answer.
