A system is shown in the End `B` of string is moving upwards with `sqrt3 m//s` Pulley is moving with speed `2 sqrt3 m//s` in direction shown in the figure. The velocity of the block A is `x + 2sqrt3 (m//s)` find x
.

Text Solution

Verified by Experts

The correct Answer is:
3
Use pulley constant equation :
`-V_(A)+(sqrt3)/(2) V_(P) +V_(B) + (V_(P))/(2)=0`
where: `V_(P) =2sqrt3, V_(B) =sqrt3 m//sec`
`V_(A) (3+2 sqrt3) m//sec`.
