A 73 kg person is riding in a car moving at 20 m/s when the car runs into a bridge abutment. Calculate the magnitude of the average force (in Newtons) on the person if he is stopped by a padded dashboard that compresses an average distance of 0.16 m

The magnitude of average force

Explanation:

Given :

Mass of person Kg

Initial velocity of car  

Average distance m

According to the second law of newton.

From the kinematic equations,

Where initial velocity, in our case final velocity is zero ()

So average force is given by,

N

But magnitude of average force is,

N

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
