An unusual spring has a restoring force of magnitude f = (2.00 n/m)x + (1.00 n/m2)x2, where x is the stretch of the spring from its equilibrium length. a 3.00-kg object is attached to this spring and released from rest after stretching the spring 1.50 m. if the object slides over a frictionless horizontal surface, how fast is it moving when the spring returns to its equilibrium length?
