How do I solve this problem?

Problem 1 [25 points] Show all relevant work! The figure shows a cord attached to a cart of mass 4.8 kg that can slide along a horizontal rail aligned along an x axis with friction. The left end of the cord is pulled over a pulley, of negligible mass and friction and at cord height h = 1.5 m, so the cart slides from x1 = 4.0 m to x2 = 1.0 m. During the move, the tension in the cord is a constant 27.0 N and 0 = 34.58 a) [7 points] If the coefficient of static friction is /s = 0.35, determine if it is possible for the cart to move with the applied tension. (b) [5 points] What is the work done on the cart by the tension force during the displacement? (c) [6 points] If the coefficient of kinetic friction is uk = 0.15, what is the work done by the kinetic frictional force during the displacement? (d) [7 points] What is the change in the kinetic energy of the cart during the displacement
