Question

Three blocks A, B, C having masses 2m,m and 3m respectively are on a smooth

horizontal surface. Block B is given a velocity 0   20 / m s towards right, while A

and C are at rest.

A B C

0

If co-efficient of restitution for all collisions is 1

2

e  , find velocity of block B in

m/s, after all collisions.​

Answer 1

sorry i have not understood

Answer 2

Answer;

three blocks with masses m, 2m, and 3m are connected by strings. after an upward force F is applied on block m, the masses move upward at constant speed v. all blocks are moving with constant velocity. so net force on all blocks are zero.
