An object of mass m is allowed to fall from rest along a rough inclined plane. The speed of the object on reaching the bottom of the plane is proportional to

A

`m^0`

B

`m`

C

`m^2`

D

`m^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
A
`m gh - mu m g cos theta ((h)/(sin theta)) = 1/2 m v^2 implies v = sqrt(2gh (1 - mu cos theta)) implies v` is independent of m.
