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?

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.

it is called kinetic energy

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
