A 175-g object is attached to a spring that has a force constant of 76.5 N/m. The object is pulled 9.75 cm to the right of equilibrium and released from rest to slide on a horizontal, frictionless table. Compute the maximum speed of the object.
Discover the locations of the object when its velocity is one-third of the maximum speed. Treat the equilibrium position as zero, positions to the left as negative, and positions to the right as positive
