Two particles A and B are moving as shown in the figure. Their total angular momentum about the point O is: 6.5 kg AⓇ 1.5m O 2.2m/s 2.8m 3.6m/s B 3.1 kg

A disc (thin cylinder) of mass 0.05 kg and radius 0.65 m is rotating on a frictionless axle at a constant rate of 77 RPM. What a the angular velocity and angular momentum of the disc? の = rad/s L = kg-m2 A second disc of 0.02 kg and 0.23 m is dropped down the axle on top. The two then rotate together. What is the final angular velocity and RPM of the system of discs? rad/s RPM = RPM

A light rigid rod of mass 3.00 kg and length 2.00 m rotates about an axis perpendicular to its length and passing through its center as shown in the figure below. Two particles of masses m1 = 6.00 kg and m2 = 3.50 kg are connected to the ends of the rod. What is the angular momentum of the system if the speed of each particle is 4.05 m/s? m2

A thin rod with a length of 4.0 m and a mass of 4.2 kg is initially at rest. It is capable of spinning around a frictionless axle that goes through the top of the rod. A 2.5 kg mass of clay collides perfectly idealistically with the bottom of the rod. The clay was traveling perfectly horizontally with a speed of 12 m/s before the collision. How fast will the rod with the clay attached to it rotate around the axle in radians per second? The only external force on the clay/rod system come from the axle, which exerts no torque about itself.
