Question

Two blocks connected by a rope of negligible mass are being dragged by a horizontal force (see figure below). Suppose F = 68.0 N, m1 = 12.0 kg, m2 = 18.0 kg, and the coefficient of kinetic friction between each block and the surface is 0.100.

(a) Draw a free-body diagram for each block.

(b) Determine the tension T and the magnitude of the acceleration of the system.
