3. A mass m (2.0 kg) is attached to a horizontal spring of spring constant k (25 N/m) which is held stretched a distance x = 0.25 m from its relaxed position by a force, and then released. The spring compresses, pulling the mass. Assume there is no friction. a. Determine the speed of the mass when the spring returns to its relaxed position. b. Determine the speed of the mass when the spring is compressed by x/2.
