A race car accelerates from 50 m/s to 75 m/s over a distance of 400 m. What is the race car's acceleration?

Explanation:

Given that,

Initial velocity, u = 50 m/s

Final velocity, v = 75 m/s

DIstance, d = 400 m

We need to find the acceleration of the car. Let the acceleration of the car be a. We can use the third equation of motion to find it as follows :

So, the acceleration of the car is .

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
