Find slag of the body's suspension due to additional weight on the body.
A 1200 kg car carrying two 110kg football players travels over a bumpy "washboard" road with the bumps spaced 3.10 m apart. The driver finds that the car bounces up and down with maximum amplitude when he drives at a speed of 4.2 m/s (approx 9.4 mph). The car then stops and picks up three more 110kg passengers.
By how much does the car body sag on its suspension when these three additional passengers get in?
