Practice it

A diver of mass m drops from a board 14.0 m above the water's surface, as shown in the figure. Neglect air resistance.

(a) Use conservation of mechanical energy to find his speed 7.00 m above the water's surface.

Your response differs from the correct answer by more than 10%. Double check your calculations. m/s

(b) Find his speed as he hits the water.
m/s

Use the values from PRACTICE IT to help you work this exercise. Suppose the diver vaults off the springboard, leaving it with an initial speed of 3.96 m/s upward. Use energy conservation to find his speed when he strikes the water.
