In the arrangement shown, velocity of block A is 10 m/s at a moment. Then the velocity of block B at this instant is :

A

10 m/s

B

20 m/s

C

16 m/s

D

25 m/s

Verified by Experts

The correct Answer is:

D

`V_(A) = (V_(1) + 0)/(2)`
`implies V_(1) = 20 m//s`
`V_(B) cos 37^(@) = V_(1)`
`implies V_(B) = 25 m//s`
