A 60-kilogram diver dives off a board that is 5.0 m above the surface of water; he touches the bottom of a pool 3.0 m below the surface of the water. What are (a) the potential energies of the diver relative to the water surface when he is on the board and at the bottom of the pool? (b) The change in the diver's potential energy relative to the board, to the waters surface, and to the bottom of the pool?

A diver is performing on the 10 meter board at a Olympic style pool(A board that is 10 m above the water surface). She runs along theboard a 4.5 meters per second and exits the end. On her way to thewater she does a half gainer followed by one and a halfsummersaults. What is her speed when hitting the water? On arrivinghead first at the water, the diver maneuvers and finally comes to astop in a horizontal orientation touching the bottom of the 3 meterdeep diving circle of the pool, having traveled 5 meters sinceentering the water surface. What was the force stopping the diverafter her entry? Assume the diver has a mass of 63 Kilograms, andis 1.7 meters tall. Also assume that her center of mass is half waybetween her feet and the top of her head.

Consider the situation in the figure a student diver- a student diver in a pool and an instructor in the edge, outside the water. Since the indices of refraction of air and water are different, the light rays coming from the diver and the instructor are refracted at the surface, changing their apparent position with respect to each other. The diver sees the instructor at an apparent angle of measured from the normal to the interface.

(a) Find the height of the instructor's head above the water in meters, noting you will have to first calculate the angle of incidence ( for air, for water)

(b). Find the apparent depth of the diver's head below the water as seen by the instructor in meters, assuming the diver and his image both have the same horizontal distance along the surface of the water.
