A 72.0 kg swimmer jumps into the old swimming hole from a tree limb that is 3.55 m above the water.

A) Use energy conservation to find his speed just as he hits the water if he just holds his nose and drops in.

-> 8.34 m/s

B) Use energy conservation to find his speed just as he hits the water if he bravely jumps straight up (but just beyond the board!) at 2.55 m/s

C) Use energy conservation to find his speed just as he hits the water if he manages to jump downward at 2.55 m/s
