Question

Assume that 2 bodies collide head on. The graphs of their velocities with time are shown in Column-I. Match them with the appropriate situation in Column-II.

List - I	List - II
(A)	(P) m1<m2 approaching, 0<e<1
(B)	(Q) m1 hits a massive wall
(C)	(R) putty hits a ball (sticking)
(D)	(S) m1=m2, v1>v2 same direction, e=1
	(T) m1>m2 approaching, e=1

TestHub · Accepted Answer

Merging velocities means the bodies stick: putty-ball perfectly inelastic, so B $\to$ R.

Body 2 unchanged while body 1 reverses past zero means a massive wall, so C $\to$ Q.

Equal masses exchange velocities (both stay positive) in an elastic chase, so A $\to$ S.

Heavier $m_{1}$ gets reversed by the incoming $m_{2}$ while $m_{2}$ rebounds faster: head-on elastic with $m_{1} > m_{2}$ , so D $\to$ T.

Answer: A $\to$ S; B $\to$ R; C $\to$ Q; D $\to$ T
