Question

ek ball le k jb hum diwal pe marte hain to wah diwal se takrati hain toh wapas aate time ball kon sa force mahsus krta h aur kyu reply me​

Answer 1

hope it helped you

Explanation:

According to Sir Isaac Newtons third law of motion, "For every action force, there is an equal reaction force in the opposite direction." What this means is when you exert a force upon the wall, as the ball does when it strikes it, the wall exerts an equal force back...

Answer 2

Answer:

Explanation:

For simplicity let’s assume that the ball is moving with a velocity, v, towards the wall, hits the wall normally and then rebounds at a velocity of -v.

The change in velocity of the ball is:

v - (-v) = 2 v

So its change in momentum is 2 m v.

If the ball is in contact with the wall for t seconds than the change in momentum per second is:

2 m v / t

By Newton’s 2nd law: Force = change in momentum per second

So, Force on ball = 2 m v / t

By Newton’s 3rd law the force on the wall is equal to this but in the opposite direction.

So the force on the ball is 2 m v / t in the direction that the ball was travelling after impact.

The force on the wall is 2 m v / t in the direction that the ball was originally travelling.
