A wooden box weighing 15N is being pushed across a concrete floor at a constant velocity. If the coefficient of friction of kinetic friction is 0.62 what is the frictional force?
To calculate the frictional force, we'll need to use the formula:
frictional force = coefficient of friction * normal force
In this case, the normal force is the force exerted by the floor on the box, which is equal to the weight of the box. Since the box weight is given as 15N, the normal force is also 15N.
Now, we can plug in the values into the formula:
frictional force = 0.62 * 15N
frictional force = 9.3N
Therefore, the frictional force acting on the wooden box is 9.3N.
