1. A) Write down Newton's second law for a damped harmonic oscillator and identify the terms. B) Assume a general solution: x(t) = exp{-at} [ASin(@t) +BC0S(@t)], and describe in one sentence how we solve for a and @. Simply state the answer for these two variables. C) Assume a spring constant of 4.00-N/m and a mass of 4.00-kg and determine what is required for CRITICALLY damped motion. Graph x(t) if x(0) = 10 cm and it is at rest for this critically damped case.
