A motorcycle spiraling around a field executes circular motion. The circular path has a radius of 0.4 m and the motorcycle has velocity of 37 m/s. What is the angular momentum of the motorcycle about the origin?

moves e locity at constant m towards a thin cylinder of f mass M and Radins R which is fixed vertical axis d < R. M is at rest mounded on a as shown. be dore m hits it and sticks to its edge. Find the angular speed of the system just after m sticks to the edge of the aylinder. M- top view: M

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.

A playground merry–go–round has a mass of 132 kg and a radius of 1.60 m and it is rotating with an angular velocity of 0.500 rev/s. What is its angular velocity after a 19.0–kg child gets onto it by grabbing its outer edge? The child is initially at rest.

Cut off says initially, he has zero angular momentum mas he is simply...

A 95.5 kg horizontal circular platform rotates freely with no friction about its center at an initial angular velocity of 1.75 rad/s. A monkey drops a 8.65 kg bunch of bananas vertically onto the platform. They hit the platform at of its radius from the center, adhere to it there, and continue to rotate with it. Then the monkey, with a mass of 22.1 kg, drops vertically to the edge of the platform, grasps it, and continues to rotate with the platform. Find the angular velocity of the platform with its load.

A 87.5 kg horizontal circular platform rotates freely with no friction about its center at an iñitial angular velocity of 1.53 rad/s. A monkey drops a 8.75 kg bunch of bananas vertically onto the platform. They hit the platform at of its radius from the center, adhere to it there, and continue to rotate with it. Then the monkey, with a mass of 21.1 kg, drops vertically to the edge of the platform, grasps it, and continues to rotate with the platform. Find the angular velocity of the platform with its load.
