Answer to Question #53907 in Classical Mechanics for Matthew garner

Question

An object that has mass m=2 kg is placed on a plane having an inclination to the horizontal of α = 30O. The coefficient of friction between the object and the surface is 0.3. Find the horizontal force necessary to act on the object that would cause the object to move up the slope with a constant speed.
This is the answer I got.
Force that is making the mass to tend to slide along the slope= mgsinα=2x9.8xsin30=9.8N

Friction force Fr= mgcos=0.32x9.8xcos30=5.09

Force parallel to plane to overcome resisting force=T=mgcos+ mgsinα=9.8+5.09=14.89N
F=T/cos=14.89/(cos30)=17.19N
