A block B is pushed momentarily along a ...

A block `B` is pushed momentarily along a horizontal surface with an initial velocity `v` . If mu is the coefficient of sliding friction between `B` and the surface, block `B` will come to rest after a time:

A

`v//g`

B

`v//(gmu)`

C

`gmu//v`

D

`g//v`

Text Solution

Verified by Experts

The correct Answer is:
B
By using v=u+at ,
`0=v-mu"gt" implies t=(v)/(mug)`

Asseration : A block of mass m starts moving on a rough horizontal surface with a velocity v. It stops due to friction between the block and the surface after moving through a ceratin distance. The surface is now tilted to an angle of 30^@ with the horizontal and same block is made to go up on the surface with the same initial velocity v. The decrease in the mechanical energy in the second situation is small than the first situation. Reason : The coefficient of friction between the block and the surface decreases with the increase in the angle of inclination.
