Homework Statement
A superball is to bounce elastically back and forth between two rigid walls at a distance d from each other. neglecting gravity and assuming the velocity of superball to be horizontal .Find the average force being exerted by the superball on each wall is ?
Homework Equations
The Attempt at a Solution
We consider rightwards direction to be positive .
If the ball moves at velocity v towards right wall then after collision it moves with velocity -v towards right.
The change in momentum of the ball is -2mv .The change in momentum of the wall is 2mv .
But we do not know the time of collision , so how do we calculate rate of change of momentum and hence force ?
