In a physics experiment, a mass is attached to a spring and set in motion on a frictionless surface. It is observed that the mass takes π seconds to complete one full oscillation. The mass moves a total of 40 centimeters from its leftmost to its rightmost position, and the equilibrium point is the midline. Which function x(t), with position in centimeters and time t in seconds, models this motion?
- x(t) = 40sin(2t)
- x(t) = 20sin(t)
- x(t) = 20sin(2t)
- x(t) = 40sin(t)
