If we have a ball which we throw toward a wall which touches the wall and bounces back then how will you calculate the force applied by the wall on the ball because the the contact time of the ball and the wall is infinitely small so force must be infinitely large?
In a similar case If a ball is dropped from a height of 80cm (10kg ball), What amount of force will the ground apply on the ball(suppose ball comes to halt after touching the ground)?
In both the cases the duration of change of momentum is infinitely small so should the force be infinitely large ??
