Two blocks connected by a light horizontal rope sit at rest on a horizontal, frictionless surface. Block A has mass 17.0 kg, and block B has mass m. A constant horizontal force F = 60.0 N is applied to block A (Figure 1). In the first 5.00 s after the force is applied, block A moves 18.0 m to the right.
While the blocks are moving, what is the tension T in the rope that connects the two blocks?
