A giant yo-yo has a mass of 2 kg and a moment of inertia of 1.28 kgm2. The central spool has a radius of 0.4 m. As it falls, the string unwinds from the central spool without slipping. If the yo-yo is released from rest, how fast will it be moving when it has fallen a distance of 1.5 meters?

    One simple way to measure the moment of inertia of an irregular object is shown in the diagram. The object is mounted on a frictionless axis. A light string is wrapped around the object, passes over a light pulley (so it has negligible moment of inertia itself), and then connected to mass M = 40.6 kg. The system is released from rest. After mass M has fallen distance 4.05 m it is moving 2.67 m/s and the object has reached...

    Mike COD Meteorology .. Tropical Tidbits Gmail Twitter Apps hysics Course Home <Homework-7 Practice Problem 9.9 In this example we will apply conservation of energy to a simplified version of a yo-yo. We will need to account for the fact that the yo-yo has both translational and rotational kinetic energies as it unwinds from the string. (Figure 1) shows our primitive (and not very practical) yo-yo in the form of a solid disk with radius Rrand total mass M. It...
