Tonight's homework is as follows:

A stationary 15 kg object is located on a table near the surface of the earth. The coefficient of kinetic friction is 0.25. A horizontal force of 40 N is applied to the object.

Draw a free body diagram with the forces to scale.

Determine the force of friction.

Determine the acceleration of the object.

If you wanted to watch the mythbusters again, here it is.
