A 60 kg skydiver dives straight down like an arrow. They can be treated as a streamlined body with a drag coefficient of 0.4 and a circular cross sectional area with a radius of 20 cm. The density of air is about 1.204 kg/m. They pull their parachute tags and the parachute is a hollow hemisphere with a drag coefficient of 1.42 and a circular cross sectional area with a radius of 3 meters. a. Calculate the terminal velocity of the skydiver while diving. b. Calculate the terminal velocity of the skydiver with their parachute deployed.
