The suspension of a car may be considered to be an ideal spring under compression.
When the driver, of mass m1, steps into the car, of mass m2, the vertical height of the car above the road decreases by x.
If the car is driven over a series of equally spaced bumps, the amplitude of vibration becomes much larger at one particular speed.
Explain why this occurs and find an expression for the separation, d of the bumps if it occurs at a speed of v .
im assuming "amplitude of vibration" just means resonant frequency
I can find an equation for spring constant k of the spring
but im not sure what to do next.
