Question

elasstic collisions in two dimensions derevaion​

Answer 1

Two dimensional elastic collisions are very common on the subatomic level. Suppose that a proton traveling with some initial velocity collides with another proton that is stationary. Following the collision, the two objects travel in different directions and with different velocities.

Answer 2

Answer:

all collisional interactions momentum remain conserved. Collisions are called elastic collisions if, in addition to momentum conservation, kinetic energy remain conserved too. To derive the elastic collision equations we make use of the Momentum Conservation condition and Kinetic Energy Conservation condition.
