A student stands on a platform that is free to rotate and holds two dumbbells, each at a distance of 65 cm from his central axis. Another student gives him a push and starts the system of student, dumbbells, and platform rotating at 0.50 rev/s. The student on the platform then pulls the dumbbells in close to his chest so that they are each 22 cm from his central axis. Each dumbbell has a mass of 1.00 kg and the rotational inertia of the student, platform, and dumbbells is initially 2.40 kg-m². Model each arm as a uniform rod of mass 3.00 kg with one end at the central axis; the length of the arm is initially 65 cm and then is reduced to 22 cm. What is his new rate of rotation?

John McClane, desperately trying to escape the bad guys in an upper floor of a skyscraper, grabs a fire hose and crashes out a window. He falls toward the ground, dragging the hose with him. The hose is wound around a cylinder that has a moment of inertia equal to 5 kg m2, and the hose unspools from the cylinder as McClane falls. Assuming that the hose is pulled from the cylinder at an angle that is perpendicular to the cylinder's radius, what is McClane's acceleration? Let McClane's mass be 75 kg and the radius of the cylinder be 0.5 m. Neglect friction and air resistance. Hose Wall Spool McClane

A pulley has a negligible mass (that means, the radius is not relevant). It is supported with a pin at the center (and is free to rotate). A rope goes over the pulley. Block A, which has a mass of 5.723 kg is connected to one side of the rope. On the other side, Block B, with a mass of 12.602 kg is connected. The system is released from rest. What is the speed of block B, after B has traveled 0.716 m? Please enter a positive value in m/s (but without units) regardless of the direction of the motion of B
