string 30 N m1 m2 In the figure above, two blocks are connected by a massless string and slide along a frictionless horizontal surface. Block 1 has mass m1=10 kg and block 2 has mass m2=5 kg. A force of 30 N is applied to block 2 as shown. (a) For m1, draw the free-body diagram, and write out E F = max. (b) Draw the free-body diagram for the string. (c) For m2, draw the free-body diagram, and write out E F, = maz. (d) For the combined system consisting of m1+string+m2, draw the free-body diagram (there should be just three forces). Then write
