  1. Oct 22, 2006 #1
    i have a question on what fromula i would need to do this problem i have been trying for thje last half hour and have come up with little to nothing

    What force would be needed to accelerate a 35 kg mass up a 25 degree incline at 3 m/s/s if the coefficient of friction is .11?

    i drew a FBD with triangle and the inner right triangle with sin and cos. ive tried F=ma and cant come up with anything. i need and answer very soon please, if possible.its a take home test:)

    The only formula you need is Fnet = ma. What does all your work look like?
