In practice, the suspension system of a car consists of a spring under compression
combined with a shock absorber which damps the vertical oscillations of the car. Draw sketch graphs, one in each case, to illustrate how the vertical height of the car above the road will vary with time after the car has just passed over a hump if the shock absorber is:
(i) not functioning.
(ii) operating normally.
When the driver of mass 80 kg, steps into the car of mass 920 kg, the vertical height of the car above the road decreases by 2.0 cm. If the car is driven over a series of equally spaced humps, the amplitude of the vibration becomes much larger at one particular speed.
(i) Explain why this occurs. ( I understand that this happens due to resonance)
(ii) Calculate the separation of the humps if it occurs at a speed of 15 ms-1.
Please tell me the answers to these questions.
