(a) A device consists of an object with a weight of 40.0 N hanging vertically from a spring with a spring constant of 210 N/m. There is negligible damping of the oscillating system. Applied to the system is a harmonic driving force of 13.0 Hz, which causes the object to oscillate with an amplitude of 3.00 cm. What is the maximum value of the driving force (in N)? (Enter the magnitude.) (b) What If? The device is altered so that there is a damping coefficient of b = 5.00 N · s/m. The hanging weight and spring constant remain the same. The same driving force as found in part (a) is applied with the same frequency. What is the new amplitude (in cm) of oscillation? (c) What If? Repeat the same calculation as part (b), only now with a damping coefficient of b = 100 N · s/m. (Enter the answer in cm.)

Question
(a) A device consists of an object with a weight of 40.0 N hanging vertically from a spring with a spring constant of 210 N/m. There is negligible damping of the oscillating system. Applied to the system is a harmonic driving force of 13.0 Hz, which causes the object to oscillate with an amplitude of 3.00 cm. What is the maximum value of the driving force (in N)? (Enter the magnitude.)
(b) What If? The device is altered so that there is a damping coefficient of
b = 5.00 N · s/m.
The hanging weight and spring constant remain the same. The same driving force as found in part (a) is applied with the same frequency. What is the new amplitude (in cm) of oscillation?(c) What If? Repeat the same calculation as part (b), only now with a damping coefficient of
b = 100 N · s/m.
