An object with mass 3.8{\rm kg} is attached to a spring with spring stiffness constant 220{\rm N/m} and is executing simple harmonic motion. When the object is 2.1×10?2{\rm m} from its equilibrium position, it is moving with a speed of 0.55 {\rm m/s}. Calculate the amplitude of the motion. Express answer in meters. Calculate the maximum velocity attained by the object.
[Hint: Use conservation of energy.] Express answer in meters per second
