ICL 14.61 .. CALC The motion of an underdamped oscillator is described by Eq. (14.42). Let the phase angle o be zero. (a) According to this equation, what is the value of x at t = 0? (b) What are the magnitude and direction of the velocity at t = 0? What does the result tell you about the slope of the graph of x ver- sus t near t = 0? (c) Obtain an expression for the acceleration a, at 1 = 0. For what value or range of values of the damping constant b (in terms of k and m) is the acceleration at t = 0 negative, zero, and positive? Discuss each case in terms of the shape of the graph of x versus t near t = 0
