Question

A 105-kg rubber mat is pushed on a dry concrete floor. What is the coefficient of static friction, if the force required to start the mat sliding is 1030 N?

Answer 1

Answer:

$\mu=1$

Explanation:

Given that,

Mass of a rubber mat, m = 105 kg

We need to find the coefficient of static friction, if the force required to start the mat sliding is 1030 N.

The applied force is given by :

$F=\mu mg\\\\\mu=\dfrac{F}{mg}\\\\\mu=\dfrac{1030}{105\times 9.8}\\\\\mu=1$

So, the required coefficient of static friction is equal to 1.
