Question

Many collisions, like the collision of a bat with a baseball, appear to be instantaneous. Most people also would not imagine the bat and ball as bending or being compressed during the collision. Consider the following possibilities: The collision is instantaneous. The collision takes a finite amount of time, during which the ball and bat retain their shapes and remain in contact. The collision takes a finite amount of time, during which the ball and bat are bending or being compressed. How can two of these be ruled out based on energy or momentum considerations?

The collision is instantaneous.

Explanation / Answer

The collision takes a finite amount of time, during which the ball and bat are bending or being compressed.

Consider a rock falls on a plastic plate. The plate will break. Why? The complete system has to conserve the energy and the momentom

The same process is happening everywhere. The system has to consere both energy and momentom. When a bat hits a ball the shape of the ball is changing and energy and momentom is conserved and the shape is changed to original after some milli second it goes away from the bat.
Eventhough it may take time to come to original state but the actual time took by the whole process is very less. For a viewer it is an instantaneous process only. But when we condider the system it is taking enugh time to changing shape to conserve the energy and momentom
