An object with mass 2.6kg is attached to a spring with spring stiffness constant 260N/m and is executing simple harmonic motion. When the object is 2.1×10^?2m from its equilibrium position, it is moving with a speed of 0.45 m/s.
Part A Calculate the amplitude of the motion.
Part B Calculate the maximum velocity attained by the object. [Hint: Use conservation of energy.]
