A 1500 kg car carrying four 90 kg people travels over a "washboard" dirt road with corrugations 3.7 m apart. The car bounces with maximum amplitude when its speed is 20 km/h. When the car stops, and the people get out, by how much does the car body rise on its suspension?

Car body rise on its suspension by 0.0309 m

Explanation:

We have given mass of the car m = 1500 kg

Mass of each person = 90 kg

Speed of the car

Distance traveled by car d = 3.7 m

So time period  

Frequency

Angular frequency is

Angular frequency is equal to

k = 114109.92 N/m

Now weight of total persons will be equal to spring force

x = 0.0309 m
