Two blocks, of masses Mi and M2, are securely joined by a stiff, massless rod and rest on a frictionless surface. Two forces, F1 and F2, are applied to the two blocks as shown. M2 F1 Block 1: M1 = 3 kg Block 2: M2 = 7 kg F2 = 9N a2 = 3.7 m/s2, to the right. How does the magnitude of force, Frod,2, exerted by the rod on mass M2, compare to the magnitude of the force F1?
