Question

force of 294N is required to start moving an object of 100kg in a horizontal plane. Calculate the coefficient of friction.

​

Answer 1

Given:

Force of 294N is required to start moving an object of 100kg in a horizontal plane.

To Find:

coefficient of friction.

Solution:

Coefficient of friction, μ = F / N

Where F is the frictional force and N is the normal reaction

 N = mg

⇒ N = 100 x 9.8 = 980 N

Now, it is given that F = 294 N

Putting these values in the formula,

μ = (294 / 980) = 0.3

Hence, the coefficient of friction is 0.3
