A body of mass m moving with velocity V collides head-on with another body of mass 2m which is initially at rest. The ratio of K.E of colliding body before and after collision will be:

Question

noogler · Answer

3:1 as the particles undergom head on collision first and second body moves with cmmon velocity mv+2m(0)=(m+2m)v l ….......................by the conservation of momentum v l =v/3 initial K.E............1/2mv 2 final K.E..............1/2(m+2m)(v l ) 2 =1/2(3m)(v/3) 2 =1/6mv 2 K.E i /K.E f =3/1
