Angular Momentum
A long thin rod of mass M = 2.00 kg and length L = 75.0 cm is free to rotate about its center as shown. Two identical masses (each of mass m = .421 kg) slide without friction along the rod. The two masses begin at the rod's point of rotation when the rod is rotating at 10....

Physics Angular Momentum
A bullet with a mass m = 4.83 g and initial speed of 330 m/s passes through a wheel which is initially at rest as in the gure. The wheel is a solid disk with mass M = 2.29 kg and radius R = 18.6 cm The wheel rotates freely about an axis through its center and out of the plane ...

Physics
A ball (mass m = 250 g) on the end of an ideal string is moving in circular motion as a conical pendulum as in the gure. The length L of the string is 1.67 m and the angle with the vertical is 37 degrees A) What is the magnitude of the angular momentum (kg m2/s) of the ball ...
