QUESTION 4 Cаrt A with а mаss оf 1 200 kg is tоwing cart B alsо with a mass of 1 200 kg with a tow rope as shown on the diagram below. They are moving across a rough horizontal surface, with a force of magnitude F. Ignore the mass of the rope. The coefficient of kinetic friction for the cart A and cart B, are 0,2 and 0,1 respectively. Right click on the button below to open the image in a new tab. 4.1 State Newton’s second law in words. (2) 4.2 Draw a free body diagram of all the forces acting on cart A. (5) 4.3 Calculate the tension in the string if the system accelerates to the right at 4 m.s-2. (5) 4.4 Calculate the magnitude of the force F if the system moves to the right at constant velocity. (6) [18]
