Question

what is elastic motion in 2d????​

Answer 1

An elastic collision is a collision in which there is no net loss in kinetic energy in the system as a result of the collision. Both momentum and kinetic energy are conserved quantities in elastic collisions. Suppose two similar trolleys are traveling toward each other with equal speed.

Hope this was helpful!! :)

Answer 2

Answer:

Elastic collision of equal masses in two dimensions - example. Let a body of mass m collide with an object of same mass at rest. Let its velocity be un along the normal before collision and ut along the tangent. Using conservation of momentum in tangential direction, mut=mv1,t.
