Question

A diver of mass 40 kg dives from rest from a diving platform at a height of 10 m from the water surface. Calculate her kinetic energy, potential energy and total mechanical energy when she is at a height of 3 m from the water surface.

Answer 1

Answer:

•Potential energy=400joule

•Kinetic energy=180joule

•total mechanical energy=400+180=580 joule
