A boy of mass 30.3 kg, jumps off a diving platform2.38 m high. He lands in the water and goes under a distance1.48 m, before he stops.
a: What is the boys initial potential energyusing the lowest point he reaches as the reference height(h=0)?
b: What is the boy's velocity when he hits the water?
c: What is the magnitude of the resistive forceof the water on the boy?
