An object attached to a horizontal spring is oscillating backand forth along a frictionless surface. The maximum speed is 1.25m/s, and its maximum acceleration is 6.89 m/s2 . How much time elapses between an instant when the object's speed is ata maximum and the next instant when its acceleration is at amaximum?
