System is shown in the figure. Velocity of sphere A is 9 `(m)/(s)`. Find the speed of sphere B.

A

`9(m)/(s)`

B

`12(m)/(s)`

C

`9xx(5)/(4)(m)/(s)`

D

none of these

Text Solution

Verified by Experts

The correct Answer is:
B

`9cosalpha=vsinalphararr` ..(i)
`(19-R)/(12)=tanalpha`
`(R+5)=(12)^2+(19-R)^2` ..(ii)
`impliesR=10`
Hence from (i) and (ii) `v=12(m)/(s)`
