Block A and C starts from rest and move ...

Block A and C starts from rest and move to the right with acceleration `a_(A)=12tms^(-2)` and `a_(C )=3ms^(-2)`. Here t is in second. The time when block B again comes to rest is

A

1s

B

`(3)/(2)s`

C

2s

D

`(1)/(2)s`

Text Solution

Verified by Experts

The correct Answer is:
A
Taking A and B as system friction because of grob
`f_("max")impliesmuxxNimplies0.5 xx200implies100N`
