A block slides down as incline of 30^@ ...

A block slides down as incline of `30^@` with the horizontal. Starting from rest, it covers 8 m in the first 2 seconds. Find the coefficient of static friction.

Text Solution

Verified by Experts

Use ` s = ut + 1/2 at^2`
` a = (2s)/(t^2) " as " u= 0 `
`mu = (g sin theta)/(g cos theta) `
Putting the value and solving `mu = 0.11`
