Question

A 56.0 kg diver strikes the water at a speed of 13.9 m/s, then slows to a stop underwater in 0.65 s What is the momentum of the diver as she strikes the water?

Answer 1

Answer:

the momentum of the diver is 778.4 m/s.

Explanation:

Given;

mass of the diver, m = 56 kg

speed at which the diver strikes the water, v = 13.9 m/s

duration of the motion, t = 0.65 s

The momentum of the diver is calculated as follows;

P = mv

P = 56 x 13.9

P = 778.4 m/s

Therefore, the momentum of the diver is 778.4 m/s.
