Suppose the diver vaults off the springboard, leaving it with an initial speed of 3.82 m/s upward. Use energy conservation to find his speed when he strikes the water.
___ m/s
Use the values from PRACTICE IT to help you work this exercise
which the values are
A diver of mass m drops from a board 12.0m 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
10.84 m/s (this is right)
(b) Find his speed as he hits the water.
15.34 (this is right)

A springboard diver with a weight of wt 110 lbs performs a jump from a s 10 m diving platform. Her COG is d - 0.8 m above the platform surface. a) What is her potential energy before takeoff. (NOTE: Consider the position of the COG for your calculations). b) Assuming she jumps feet-first, what will be the diver's speed (in mph) the moment right before her feet enter the water? (2 pts.) (2 pies.)
A lowly high diver pushes off horizontally with a speed of 2.50 m/s from the edge of a platform that is 10.0 m above the surface of the water.
