An object with mass 3.0kg is attached to a spring with spring stiffness constant k=280N/m and is executing simple harmonic motion. When the object is 0.020m from its equilibrium position, it is moving with a speed of 0.55m/s.
a) Calculate the amplitude of the motion.
b) Calculate the maximum velocity attained by the object.
