Lecture 10, #2 - Conservation of Angular Momentum PROBLEM DESCRIPTION |
An astronaut (mass 120 kg) doing a space walk is about to grab onto a spinning satellite of mass 500 kg, and moment of inertia 300 kg-m2. Before grabbing the satellite, the astronaut is not rotating at all, and the satellite is rotating with an angular velocity of 5.0 rad/s. The astronaut then grabs the satellite and the two rotate together. After grabbing the satellite, the moment of inertia of the combined astronaut/satellite system is 400 kg-m2. Calculate the new angular velocity of the astronaut/satellite.
