PhysicsQ&A Library31. Three objects are connected on a table as shown in Fig- QCure P5.31. The coefficient of kinetic friction between the block of mass m and the table is 0.350. The objects have masses of m 4.00 kg, m 1.00 kg, and m 2.00 kg, and the pulleys are frictionless. (a) Draw a free-body diagram of each object. (b) Determine the acceleration of each object, including its direction. (c) Determine the tensions in the two cords. What If? (d) If the tabletop were smooth, would the tensions increase, decrease, or remain the same? Explain тэ тi mgQuestion
