Q1. A 1200 kg car carrying four 87kg people travels over the rough "washboard" dirt road with corrugations 4.0 m apart which causes the car to bounce on its spring suspension. The car bounces with maximum amplitude when its speed is 18km/h. The car now stops, and the four people get out. By how much does the car body rise on its suspension owing to this decrease in weight?

Q2. A parachutist and her parachuting equipment have the combined mass of 121 kg. Her terminal velocity is 5.30 m/s with the parachute open. Her parachute has a cross-sectional area of 35.80 m^2. The density of air at that altitude is 1.23kg/m^3. What is drag coefficient of the parachutist with her parachute? (The answer should be 1.60)
