An object attached to a horizontal spring is oscillating back and forth along a frictionless surface. The maximum speed of the object is 1.27 m/s, and its maximum acceleration is 8.41 m/s2. Determine how much time elapses between an instant when the object's speed is at a maximum and the next instant when its acceleration is at a maximum?
