Questions
A mass m moves with a velocity v and collides in elastically with another identical mass. After collision, the first mass moves with velocity in a direction perpendicular to the initial direction of motion. Find the speed of the second mass after collision.
detailed solution
Correct option is A
In – x direction mv2cosθ =mv --- (1)In – y direction mv2sinθ=mv3 --- (2)Squaring and adding (1) and (2)v2 = 2v/3Talk to our academic expert!
