) has a radius of 10 cm and a mass of 2 kg rotated
on its axis with an angular velocity of 20 rad/s in a horizontal position. Another disc
which has the same radius but a mass of 1 kg is dropped by exactly one axis
with the first disc so that it rotates together.
Define:
a. first disc angular momentum !

Attached to the ends of the rod are two masses with masses m1 = 3.8 kg and m2 = 3.3 kg. The combination rotates in the xy plane about a pivot through the center of the fod. Determine the angular momentum of the system about the centre when the speed of each particle is 4.0 m/s.arrow_forward3. The figure to the right shows a rod that is connected to a frictionless table through a pin-labeled by A -placed through the center of it. (You are looking down on the table.) The rod has mass m and length l. Although the rod is initially at rest, it can rotate freely (without friction) about the pin. A small particle with mass m/3, and moving with an initial velocity vo vo collides with the end of the rod. After the collision the mass stops moving, and the rod starts rotating with angular velocity w. I would strongly recommend that you draw a free body diagram for the rod in parts a and b. a. Linear momentum is not conserved for this collision. Explain in detail why. b. Angular momentum is conserved about the pivot. Explain in detail why. c. What is w? Express it in terms of vo, and l. d. Is energy conserved in the collision? Justify your answer by calculating the change in energy of the system in the collision. e.
