Question 2. A 3.00 kg object is fastened to a light spring, with the intervening cord passing over a pulley as in Figure 1. The pulley is frictionless, and its inertia may be neglected. The object is released from the rest when the spring is unstretched. If the object drops 10.0 em before stopping, find a) the spring constant of the spring and bjthe speed of the object when it is 5.00 cm below its starting point. 3.00 kg WWW Figure 1: Pulley spring system
