A vertical spring-mass system undergoes damped oscillations due to air resistance. The spring constant is 2.85 x 104 N/m and the mass at the end of the spring is 15.6 kg. (a) If the damping coefficient is b = 4.50 N s/m, what is the frequency of the oscillator? 6.8 ✔ Hz (b) Determine the fractional decrease in the amplitude of the oscillation after 3 cycles. 0.041 X What is the amplitude term for a damped oscillator represented by the expression x = Ae-(b/2m)t cos(wt + p)? How can you express the time t in terms of the period of oscillation for 3 cycles? Additional Materials Reading
