To find the magnitude of the frictional force acting on the object, we can use the formula for the frictional force due to kinetic friction:

 

Where:

is the coefficient of kinetic friction.

is the normal force.

 

1. Calculate the normal force ():

Since the object is on a horizontal surface and there is no vertical acceleration, the normal force is equal to the weight of the object:

 

Where:

(mass of the object)
