Block A of mass 2.0 kg is pulled along a horizontal table by a force of 15 N, which is applied by a light string that passes over a light frictionless pulley, as shown above. The coefficient of kinetic friction between the block and the surface is 0.25. (a) On the dot below, which represents the block, draw and label the forces (not components) that act on the block as it is pulled across the table. (b) Calculate the acceleration of the block. A 2.0 kg B 1.5 kg The applied force is removed. Block B of mass 1.5 kg is now attached to the string, as shown above. The system is released from rest so that the 1.5 kg block descends and the 2.0 kg block is pulled again across the table. (c) Calculate the acceleration of the 1.5 kg block as it descends. (d) Calculate the tension in the string connecting the two blocks. (e) Calculate the distance that the 1.5 kg block descends in 0.40 s.
