Part A Spinning Mass on a Spring Given the angular speed w, find the radius R(w) at which the mass rotates without moving toward or away from the origin An object of mass M is attached to a spring with spring constant k whose unstretched length is L, and whose far end is fixed to a shaft that is rotating with angular speed w. Neglect gravity and assume that the mass rotates with angular speed w as shown. (Figure 1) When solving this problem use an inertial coordinate system, as drawn here. (Figure 2) Express the radius in terms of k, L, M, and ω Hints kL Submit Give Up Correct Figure 1 of 2 Part B Assume that, at a certain angular speed ω2, the radius R becomes twice L.
