ΣF = mRω2 - kx = 0
mRω2 = kx
An object of mass M = 5.00 kg is attached to a spring with spring constant k = 220 N/m whose unstretched length is L = 0.180 m , and whose far end is fixed to a shaft that is rotating with an angular speed of ω = 2.00 radians/s . Neglect gravity and assume that the mass also rotates with an angular speed of 2.00 radians/s
Assume that, at a certain angular speed ω2, the R becomes twice L. find ω2 in radians/s
