Given: lambda = 10 m, mass of the vehicle, m= 1000kg, k=9000 N/m, speed 60/2pi m/s. Interpret this graph for me. What happens if we go to the right? What happens if we go to the left? If we want to have a great magnitude of vibrations according to the graph should we increase or decrease our speed? explain.  What if b is decreasing but we maintain our speed would b decrease or increase the magnitude? Why? If we are driving at the speed that always maximizes the magnitude of the shaking will decreasing b increase or decrease magnitude?

Follow-up Question

what happens when w/wn > than sqrt(2)? what happens to the damping and why did it switch, like the lower the damping the lower the vibrations? What does the magnitude directly impact?
