N/m (b) the distance (in cm) the spring stretches if you replace the 2.70 kg object with a 1.35 kg object cm (c) the amount of work (in J) an external agent must do to stretch the spring 8.40 cm from its unstretched position

A weight is attached to a spring suspended vertically from a ceiling. When a driving force is applied to the system, the weight moves vertically from its equilibrium position, and this motion is modeled by y = 1/6 sin(8t) + 1/8 cos(8t) where y is the displacement (in feet) from equilibrium of the weight and t is the time (in seconds).
