Four football players each weighing 1200N get into a car. You measure that the car sinks by an amount of 2.5cm. What is the overall spring constant for the suspension springs?
The damping is very small. It is observed that after 10.0 sec the amplitude of oscillation is 1/2 of what it was initially. Calculate the damping constant b. How does b/2m compare with the angular frequency of oscillation?
Speed bumps are separated by 9.0 meters. How fast would you need to drive to get the maximum amplitude oscillations as you pass over the bumps?
