                      6: A mass M = 0.16 /DIS(kg_u) is on a smooth horizontal surface (negligiable friction). It is attached to a spring with spring constant k = 15.3 /DIS(NPm_u). The mass is displaced from its equilibrium position (x=0) by a distance of 0.14 m (x= + 0.14 m) and then released from rest. (Give all of the correct answers, i.e., A or BC or ABC. . .)
