SOS
A man stands on a platform that is rotating (without friction) with an angular speed of 2.35 rev/s; his arms are outstretched and he holds a brick in each hand. The rotational inertia of the system consisting of the man, bricks, and platform about the central axis is 5.13 kg.m2. If by moving the bricks the man decreases the rotational inertia of the system to 1.28 kg.mp, (a) what is the resulting angular speed of the platform and (b)...

A uniform rod rotates in a horizontal plane about a vertical
axis through one end. The rod is 12.00 m long, weighs
20.00 N, and rotates at 350 rev/min clockwise when seen
from above. Calculate its rotational inertia about the axis of
rotation.

Suppose a friend is completing another physics assignment in their chair at their desk and you take the opportunity to turn this scenario into the physics question you now must complete. Your friend and chair have a combined constant moment of inertia of 5.2 kg m2, and the chair can freely rotate. Now your friend picks up two solid bricks (each of mass 1.2 kg) they accidentally collected from one of the campus buildings, and experiment with rotational kinematics. Supposing...

A man of mass 75kg stands at the center of a rotating merry-go-round platform of radius 3.0 m and moment of inertia 920 kgm^2. The platform rotates without friction with angular velocity 2.0 rad/s. The man walks radially to the edge of the platform. Calculate: the angular velocity of the system when the man reaches the edge, and the change in the kinetic energy of the system.
