Determine the time in which the smaller block reaches other end of bigger block in figure

A

`4 s`

B

`8 s`

C

`2.19 s`

D

`2.13 s`

Text Solution

Verified by Experts

The correct Answer is:
C
`f =mum_(A)` For smaller block `F -f =m_(A) a_(1)`
For larger block `f =m_(B) a_(2)`
`a_(rel) =a_(1) -a_(2), s =ut + (1)/(2) at^(2)` .
