An object with mass 3.5 is attached to a spring with spring stiffness constant 300 and is executing simple harmonic motion. When the object is 2.5×10?2 from its equilibrium position, it is moving with a speed of 0.60.
A) Calculate the amplitude of the motion.
B) Calculate the maximum velocity attained by the object. [Hint: Use conservation of energy.]
