PRACTICE IT Use the worked example above to help you solve this problem. A diver of massm drops from a board 12.0 m above the water's surface, as shown in the figure. Neglect air resistance. (a) Use conservation of mechanical energy to find his speed 6.00 m above the water's surface. m/s (b) Find his speed as he hits the water. m/s EXERCISE HINTS: GETTING STARTED I'M STUCK! 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 3.97 m/s upward. Use energy conservation to find his speed when he strikes the water. m/s
