Point B of the rod is always in contract...

Point `B` of the rod is always in contract with block and point `A` of the rod is moving parallel to ground with `5 m//s`. Block also has velocity of `5 m//c`. What will be speed of point `B` at this instant ?

A

`(15)/(2)m//s`

B

`5m//s`

C

`(5)/(2)sqrt(15)m//s`

D

`(5)/(2)sqrt(13)m//s`

Text Solution

Verified by Experts

The correct Answer is:
D
Point `B` of ………….

Constrained motion along rod
`(4v)/(5)-3=3 implies V = (15)/(2)m//s`
Speed `= sqrt(((15)/(2))^(2)+(5)^(2))`
