Three objects A, B and C are kept in a straight line on a frictionless horizontal surface. These have masses m, 2m and m, respectively. The object A moves towardsB with a speed 9 ms-1 and makess an elastic collision with it. There after, B makes completely inelastic collision with C. All motions occur on the same straight line. Find the final speed (in ms-1 ) of the object C.

There is a quantity known as coefficient of restitution which can be defined as the ratio of relative velocity of separation (after collision) and relative velocity of approach (before collision). Mathematically it can be given as shown below. Also for a completely elastic collision, e = 1 and for a completely inelastic collision, e = 0.
After 1st collision
mvA=mv′A+2mv′B
−1=v′B−v′A/0−vA ⇒v′B=6m/s
After the 2nd collision
2mv′B=(2m+m)VC⇒vC=2v’B/3⇒vC=4m/s
After 1st collision
mvA=mv′A+2mv′B
−1=v′B−v′A/0−vA ⇒v′B=6m/s
After the 2nd collision
2mv′B=(2m+m)VC⇒vC=2v’B/3⇒vC=4m/s
