# Kinetic Friction for a File Cabinet and Ice Block

1. A file cabinet weighing 1500 N is at rest on the floor. The coefficient of static friction between the floor and the cabinet is 0.5. What is the minimum force required to make the file cabinet move horizontally?

2. A force of 10 N applied to a block of ice with a mass of 10 kg moves it over a factory floor with a constant speed. What is the coefficient of kinetic friction between the block and the floor? (g = 10 m/s2).

#### Solution Preview

Hello and thank you for posting your question to Brainmass.

1. The friction force is given by:

f = mu * N

Where N is the normal force the floor applies on the cabinet, and mu is teh friction coefficient.

Now, from Newton's third law we know that the force applied by the floor on the cabinet ...
