Assignment:
A rigid rod with negligible mass has a length L= 2.6 m. The rod can rotate freely about a fixed pivot at one end. Attached at the other end of the rod is mass M1 = 8.4 kg, and at its center is mass M2 = 3.6 kg. The system is released from vertical at rest to rotate about the pivot. See a diagram showing parameters.

a. Find the velocity V1 of the end mass, and the velocity V2 of the mass at the center as the rod passes through vertical after half a rotation.
b. Find the tension T1 in the rod between the masses, and also the tension T2 in the rod betwen pivot and the center mass.
