The motor pulls in its attached rope causing an acceleration of 6m/s^2. Determine the towing force. The coefficient of kinetic friction between the 50kg crate and the plane is uk=0.3. Neglect the mass of the pulleys and the rope.
l = Sx + 2Sy
differentiate
0 = Ax + 2Ay
Ax = 12 m/s^2?
Then find the forces on the box(i.e. Ffr, N, W...), but how do you relate this to the towing force?
