A 050-Kg Object Is Attached to an Ideal Massless Spring of of Spring

Short Answer

A 0.50-kg object is attached to an ideal massless spring of spring constant 20 N/m along a horizontal,frictionless surface.The object oscillates in simple harmonic motion and has a speed of 1.5 m/s at the equilibrium position.
(a)What is the amplitude of vibration?
(b)At what location are the kinetic energy and the potential energy of the system the same?
