Question

A small lab cart and one of larger mass collide and rebound off each other. Which of them has the greater average force on it during the collision
They both experience a force of zero.


They both experience the same magnitude of the collision force.


The large cart has greater force on it.


The small cart has greater force on it.

Answer 1

When a small cart collide with a large mass then during collision they must be in contact with each other for some interval of time

During this contact interval we can say they will exert normal force on each other

This normal force is always equal and opposite on two balls which means this force will follow Newton's III law

It will be same in magnitude but opposite in the direction

So here correct answer would be

They both experience the same magnitude of the collision force.
