Swimming hole-what speed does the kid hit the water

Reference no: EM13561693

A kid drops from a tree limb 3.0 m above a swimming hole.
a) with what speed does the kid hit the water?
b) if the kid is brought to rest 1.5 m below the surface of the water, what is the magnitude of the acceleration of the child after contact with the water? assume the acceleration is constant.
