Question: A body of mass 𝑚 having an initial velocity 𝑣, makes head on collision with a stationary body of mass 𝑀. After the collision, the body of mass 𝑚 comes to rest and only the body having mass 𝑀 moves. This will happen only when

(A) 𝑚 > > 𝑀

(B) 𝑚 < < 𝑀

(D) $m=\dfrac{1}{2}M$

Answer: Option (C)

Solution:

A body of mass 𝑚 having an initial velocity 𝑣, makes head on collision with a stationary body of mass 𝑀. After the collision, the body of mass 𝑚 comes to rest and only the body having mass 𝑀 moves. This will happen only when
