The curved portions are smooth and horizontal surface is rough. The block is released from `P`. At what distance from A it will stop?

A

1 m

B

2 m

C

3 m

D

4 m

Text Solution

Verified by Experts

The correct Answer is:
A

As in the previous problem, the distance traveled by the block on the rough surface`=5m`
The block stops at distance 1m from A.

  • A block of mass 5.0kg slides down from the top of an inclined plane of length 3m . The first 1m of the plane is smooth and the next 2m is rough. The block is released from rest and again comes to rest at the bottom of the plane. If the plane is inclined at 30^@ with the horizontal, find the coefficient of friction on the rough portion.
