In the shown figure, pulleys and strings are ideal and horizontal surface is smooth. The block C (mass 2m) is given a horizontal velocity of `V_(0) = 3 m//s` towards right and the entire system is let go. Find the velocity of three blocks, just after the strings regain tension. Mass of A and B are `2m and m` respectively and take `g = 10 m//s^(2)`.

Text Solution

Verified by Experts

The correct Answer is:
`V_(A)=(36)/(7)m//s ;V_(B)=(30)/(7) m//s ;V_(C)=(33)/(7)m//s`
