Two thin rods of length L are rotating with the sameangular speed ω (in rad/s) about axes that passperpendicularly through one end. Rod A is massless but has aparticle of mass 0.66 kg attached to its free end. Rod B has a massof 0.66 kg, which is distributed uniformly along its length. Thelength of each rod is 0.77 m, and the angular speed is 5.7 rad/s.Find the kinetic energies of rod A with its attached particle andof rod B.

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...
find the error in the calculation FE4 Two identical uniform thin rigid rods are held together at one end with an electromagnet. One of the rods is attached to a fixed pivot point, around which the magnetic two rods are rotating at a constant rate (there is no gravity present here). Suddenly the connector electromagnet is tumed off, and the rod not attached to the pivot flies away. Find the percentage change in kinetic energy of the system before and...
