Incline hw problem help

  1. Nov 5, 2006 #1
    can anyone show exactly how to solve this problem with equations and all?

    a cart on wheels with a mass of 250 g has a motor driven propeller with a force P of .3 N, and it moved down an incline of 30 degrees with an acceleration of 3.5 m/s^2.

    What is the force of friction ?

    determine coefficent of friction?

    No, because it wouldn't help you. From your other post, I know your knowledge is very sketchy, and if you continue to look for shortcuts, you will come short in the exam.
