  1. there is a playroom that has springs hanging from the ceiling for children to hold on to. One child jumps up and holds one of them then after he stops bouncing, his mother pulls him downward 15 cm. with velocity 2 cm/s and let him go. Knowing that the spring constant is 21 kg/m and the child weighs 53 pounds, find the period, amplitude, frequency, and phase of motion of the spring assuming that there is no other force or friction. Note: 1kg = 2.205 lb
