An object with the mass 3.0 kg is attached to a spring with spring stiffness constant k=280 N/m and is executing simple harmonic motion. When the object is .020 meters from its equilibrium position, it is moving with a speed of 0.55 m/s.
a) calculate the amplitude of the motion
b)calculate the max velocity attained by the object
