# What do I do to get the net force

This is the question I am given:

The largest mincemeat pie ever created had a mass of 1.020 x 10³ kg. Suppose that a pie with this mass slides down a ramp that is 18.0m long and is inclined to the ground by 10.0°. If the coefficient of kinetic friction is 0.13, what is the net work done on the pie during its decent.

Ok, we just started this unit. So I know the equation for work. the displacement is 18m and the angle is 10.0°. What do I do to get the net force and how do I make the coefficient come into this problem.

since you are on to work then you know how to sum forces correct? Draw out the free body diagram, sum forces, once you have the forces summed I think you know where to go with it. If not let me know.
