a donkey pulls a cart,C, with a mass of 240Kg, attached to to a log of wood, W, with a mass of 80Kg, on a horizontal road, W is tied to the back of C by means of an inelastic rope, which is inclined at 30° to the horizontal. The donkey applies a force of 170N on cart C and the system accelerates at 0,30m.s-2 to the left. TheI force of friction on cart C is 40N. The rope has negligible mass.
a) the magnitude of the force which the rope exerts on C.
b) the force of friction on W.
