Question 10: A mass of 0.2kg attached to a spring with a spring constant of 5N/m performs simple harmonic motion. The time-dependent graph of the position of the mass with an initial velocity of 0.5m/s is shown below. If the position of the mass is expressed as x(t)=Acos(Bt+C), what is the value of the constants A, B, and C that define this motion?
