An hydraulic press has two pistons , one of 50 cm2 and the second of 250 cm2 . If in the smallest piston there is a mass of 100 N, what is the force of the second piston?

Elastic Collision

Inelastic Collision

The total kinetic energy is conserved.The total kinetic energy of the bodies at the beginning and the end of the collision is different.

Momentum does not change.Momentum changes.

No conversion of energy takes place.Kinetic energy is changed into other energy such as sound or heat energy.

Highly unlikely in the real world as there is almost always a change in energy.This is the normal form of collision in the real world.

An example of this can be swinging balls or a spacecraft flying near a planet but not getting affected by its gravity in the end.
