Three objects A, B and C are kept in a straight line on a frictionless horizontal surface. These have masses 
and m, respectively. The object A moves towards B with a speed 
and makes an elastic collision with it. Thereafter, B makes completely inelastic collision with C. All motions occur on the same straight line. Find the final speed (in 
/ s) of the object C.
Text Solution
Verified by ExpertsA
The velocity of B just after collision with A is
The collision between B and C is completely inelastic.
