An object with mass 3.7 kg is executing simple harmonic motion, attached to a spring with spring constant 280 N/m . When the object is 0.020 mfrom its equilibrium position, it is moving with a speed of 0.65 m/s .
A) Calculate the amplitude of the motion?
B) Calculate the maximum speed attained by the object?
