AXis Two spheres of mass m are attached to a light rod of length 2L. The rod is fixed at its center to a freely-rotating axis. The rod is horizontal when a small bird of mass 5m carefully lands on the right sphere. Express a answers in terms of m, L, and g (a) What is the net torque on the system the instant the bird lands (while the rod is still horizontal)? (b) Determine the angular acceleration of the system the instant the bird lands α= The system continues to rotate about the axis. At the instant the rod is vertical as shown, determine the following (c) The angular velocity of the rod ω= (d) The angular momentum of the system (e) The force that the bird must exert to stay connected to the sphere mbolic formatting help
