- (a) Calculate the magnitude of the angular momentum of the earth in a circular orbit around the sun. Is it reasonable to model it as a particle? (b) Calculate the magnitude of the angular momentum of the earth due to its rotation around an axis through the north and south poles, modeling it as a uniform sphere.a)What is the angular momentum of a figure skater spinning at 3.4 rev/s with arms in close to her body, assuming her to be a uniform cylinder with a height of 1.4 m , a radius of 16cm , and a mass of 49kg ? b)How much torque is required to slow her to a stop in 4.8 s , assuming she does not move her arms?After all the metal has unwound from the roller, the student measures the radius R and the angular speed wo of the roller to be 25 cm and 20 rad/s respectively. Observed from the side, the roller rotates counterclockwise, as shown. A piece of clay of mass m strikes the very bottom edge of the roller with a horizontal velocity v = 4.0 m/s. The clay sticks to and rotates with the roller. The clay-roller system then rotates with a final angular velocity wi. (f) Is wi greater than, less than, or equal to wo? Justify your answer.

The mass of the rod is negligible when compared to the two masses. The diameter of the rod is 8 mm and its length is 20 cm. The rod is rotating about its center (with the axis of rotation perpendicular to the length of the rod as in today's experiment). What is the moment of inertia of this system?
