Find the acceleration of block B realtiv...

Find the acceleration of block `B` realtive to the ground if the block A moves to the left with an acceleration `a_(0)`
.

A

`sqrt(31a_(0))`

B

`sqrt(25a_(0))`

C

`sqrt(30a_(0))`

D

`30a_(0)`

Text Solution

Verified by Experts

The correct Answer is:
A
`5Ta_(0)-Ta_(BA)=0,a_(BA)=5a_(0)`
`a_(B)=sqrt(a_(0)^(2)+(5a_(0))^(2)+2a_(0)5a_(0)cos60^(@)),a_(B)=sqrt31a_(0)`
