Awooden box weighing 150 n is sliding at a constant rate over a concrete sidewalk. the force required to pull the box at a steady rate is 78 n. what is the coefficient of friction?

The coefficient of friction is 0.52

Explanation:

Weight of the box, W = N = 150 N

The force required to pull the box at a steady rate is 78 N, F = 78 N

In horizontal direction, the net force acting on the box is given by :

So, the coefficient of friction is 0.52. Hence, this is the required solution.
