Consider a spring-mass system with mass m and spring stiffness k as shown in the illustration. At time t=0, the mass is displaced by P units and the velocity of the mass is zero. The displacement of the mass, x(t), is measured from the equilibrium position. Which one of the following functions represent x(t)?

- A. π πππ (βπ ππ‘)+ π π ππ(βπ ππ‘)
- B. π π ππ(βπ ππ‘)
- C. π 2 πππ (βπ ππ‘)+ π 2 π ππ(βπ ππ‘)
- D. ππππ (βπ ππ‘)
Answer: D. ππππ (βπ ππ‘)
