If it takes 35s for the tughboat to increse its speed uniformly to 25 km/h, starting from rest. The barge has a mass of 75Mg. The propeller provides the propulsion force F which gives the tughboat foward motion, where as the barge moves freely. Determine the force of the rope on the tughboat T and force F acting on the tughboat for the following cases:(a)Without the consideration of fluid resistance (b)Suppose the resistance forceon the tughboat is 0.8v^(kN)and the drag force on the bargeis 0.5v^(kN)
