SUMMARY
The discussion focuses on determining the period and amplitude of a 2.00 kg object attached to a spring, driven by an external force F=(3.00N) sin(2πt) with a spring constant of 20.0 N/m. The correct formula for the period is T = 2π√(m/k), yielding a period of approximately 1.99 seconds. The amplitude can be calculated using A = (Fo/m)/√((w^2) - (w₀^2)), where Fo is the driving force, m is the mass, and w is the driving frequency. The user, Kevin, expressed uncertainty about the equations, indicating a need to consider both the natural frequency and the driving-force frequency.
