Question

8. A particle of mass 3m initially moving with a speed u in the positive x-direction
collides with a second particle of mass m moving in the opposite direction with an
unknown speed v. After collision the mass 3m moves along the negative y-direction
with a speed u/2 and the mass m moves with a speed v" in a direction making an angle
of 45" with the positive x-direction. Determine v and v' in units of u. Is the collision
elastic?​

Answer 1

Answer:

It is elastic

Explanation:

V=45°

V= 3m
