Suppose an Olympic diver who weighs 55.0 kg executes a straight dive from a 10-m platform. At the apex of the dive, the diver is 10.8 mm above the surface of the water. 1. What is the potential energy of the diver at the apex of the dive, relative to the surface of the water? Express the answer in kilojoules to three significant figures. it is not 55.0*10.8*9.81= 5830 2. Assuming that all the potential energy of the diver is converted into kinetic energy at the surface of the water, at what speed in m/sm/s will the diver enter the water? Express the answer in meters per second to three significant figures.
