Question: K3. A mass m is attached to a spring with a spring constant k and undergoes simple harmonic motion. A mass m1 is now attached

K3. A mass m is attached to a spring with a spring constant k and undergoes simple harmonic motion. A mass m1 is now attached to m, and the period of oscillation is recorded as T1. The mass m1 is removed and a new mass m2 is attached to m, and the period of oscillation is recorded as T2. What are masses m, m1 and m2 if k = 100N/m, T1 = 2.13s, T2 = 1.55s and m2/m1 = 0.40?
