Question

Two bodies of masses `3kg` and `2kg` are connected by a along string and the string is made to pass over a smooth fixed pulley Initially the bodies are held at the saem level and released from rest. The velocity of the `3kg` body after one second is `(g =10m//s^(2))` .
A. `2m//s`
B. `1m//s`
C. `0.4m//s`
D. `4m//s`

Answer 1

Correct Answer - A
`F =ma, a = ((m_(1)-m_(2))/(m_(1)+m_(2)))g,v=u+at`
