Question

A mass m moves with a velocity v and collides inelastically 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.

Answer 1

Answer:

Explanation:

Along x-axis on cos Q =mv

Along y -axis on sin Q=mv/root3

(mv1cosQ)^2+(mv1sinQ)^2

=(mv)^2+(mv^2)/root 3

m^2v1^2=4m^2 v^2/3

So,we get v1=2/root3

Answer 2

Answer:

$v1 = \frac{2v}{ \sqrt{3} }$
