So imagine we had a rubber ball and we threw it perpendicular to the surface of wall. The ball will obviously experience some “throwing” force — horizontal with respect to floor (let’s assume the ball is in perfect vacuum and there is no net torque). As it hits the wall, the normal force will balance the force exerted by the ball and the ball will be at rest for some tiny time interval — deformed. However, since the ball is made of rubber, the molecular forces ought to return the ball to its initial shape — thus some force will be exerted on the wall — also on the ball, that will cause it to “bounce off” (technically fall parabolically because there is also gravity).
Correct me if and where I am wrong. As a high school student I sometimes find it a bit complicated to apply things to more advanced examples that I see in every day life… maybe it’s just me, I don’t know.
Also, if possible let’s try to keep this problem in domain of Newton’s laws, please don’t talk about it from the conservation of energy perspective, it won’t help me much
