A 0.35 kg object rests on a frictionless horizontal surface, where it is attached to a massless spring whose k-value equals 18.0 N/m. Let x be the displacement, wherex is the equilibrium position and x > 0 when the spring is stretched. The ob ect is pushed, and the spring compressed unti xi = - 4.00 cm. It then is released from rest and undergoes simple harmonic motion.

What is the object's maximum speed (in m/s) after it is released? ___ m/s
