A 3.1 kg bundle starts up a 30° incline with 139 J of kinetic energy. How far will it slide up the plane if the coefficient of friction is 0.30?

Post your work and I'll check it/guide you. If you're having trouble getting started try drawing a picture. Nice and BIG.
original energy=changePE+frictionenergy
=mgdistance*sinTheta+distance*mu*mg*cosTheta*distance
solve for distance
=mgdistance*sinTheta+distance*mu*mg*cosTheta*distance
solve for distance
