A 72.0 kg swimmer jumps into the old swimming hole from a tree limb that is 3.75 m above the water. 1) Use energy conservation to find his speed just as he hits the water if he just holds his nose and drops in. Express your answer in meters per second. 2) 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 2.20 m/s. Express your answer in meters per second. 3) Use energy conservation to find his speed just as he hits the water if he manages to jump downward at 2.20 m/s. Express your answer in meters
