A 0.10 kg moving with a velocity of +0.20 m/s makes an elastichead on collision

Question

A 0.10 kg moving with a velocity of +0.20 m/s makes an elastichead on collision with a 0.15kg initially at rest. What is thefinal velocity of 0.10kg object after collision? a. +0.16m/s b. -0.16ms c. +0.04ms d. -0.045 m/s e. none Can someone show me the steps? Thanks!

Explanation / Answer

given,mass, m1= 0.10kg intiall velocity of first mass = u1= 0.20m/s seconed mass , m2= 0.15kg intial velocity of seconed mass= u2= 0 after head on elastic collsion final velocity of first mass=v1= (m1-m2/m1+m2)u1+(2m2/m1+m2)u2                                    plug values then v= -0.04m/s. hope this will help you.                                    plug values then v= -0.04m/s. hope this will help you.
