Your friends are travelling at 100 km/hr in a 1081 kg car with broken shock absorbers down a smooth concrete highway in Japan. Not unexpectedly, an earthquake hits lasting 1.45 minutes with changing intensity. Naturally, your friends are wearing their seatbelts and are being pushed about so forcefully that Susie, the driver of the car, pulls over to the side of the road and tries to stop. Unfortunately, the broken shock absorbers were not dampening the oscillation making Betty and Ken feel quite upset having never experienced such an intense tremble. George, has a body mass of 88.1 kg and a height of 186 cm, is an expert of vibration and estimates that the max amplitude occurred when the shaking reached about 1.7 Hz. Betty measures 65.3 kg and 169cm, Ken 79.1 kg and 179 cm, Susie 61.5 kg and 171 cm.When the car comes to a halt, they leave the car as fast as they can.
By what distance do the car's four undamaged coil springs raise the car's body as your friends get out?
