A block of mass `2 kg` is given a push for a moment horizontally and then the block starts sliding over a horizontal plane. The graph shows the velocity`-` time of the motion. The co`-` efficient of sliding friction between the plane and the block is `:`

A

`0.02`

B

`0.20`

C

`0.04`

D

`0.40`

Text Solution

Verified by Experts

The correct Answer is:
B
The magnitude of declaration from graph is
`a=(8-0)/(4-0)=2m//s^(2)`
The declaration of block is
`a=mug :. Mu=(a)/(g)=0.2`
