A spring with spring constant k = 15.0 N/m hangs vertically from the ceiling. A 1.20 kg mass is attached to the bottom end of the spring, and allowed to hang freely until it becomes stationary. Then, the mass is pulled downward 10.0 cm from its resting position and released. At the moment of its release, what is (a) the magnitude of the mass's acceleration and (b) the direction? Ignore the mass of the spring.
