An object is gently placed on a long converges belt moving with `11 ms^(-1).` If the coefficient of friction is 0.4, then the block will side in the belt upto a distance of

A

`10.21` m

B

`15.125` m

C

`20.3` m

D

`25.6` m

Text Solution

Verified by Experts

The correct Answer is:
B
`u=11` m/s (Given)
`because a=mg`
`a=0.4xx10=4m//s^(2)`
According to question, `v=0`
So from, `v^(2)=u^(2)+2as`
`0=(11)^(2)+2(-4)xxs`
`s=(11xx11)/(8)=15.125m`
