A spring is suspended from the ceiling. When a 10 kg object is attached to the spring and then lowered until the system is in static equilibrium, the spring is observed to have stretched 40 cm. The 10 kg object is then raised 20 cm above the point where it was in static equilibrium. The object is released and it begins to move vertically in simple harmonic motion. (a) What is the spring constant of the spring? (b) What is the maximum velocity of the 10 kg object?
