A skydiver with his parachute has a combined mass of 79 kg and an approximate frontal area of 0.71 m^2.
Calculate the terminal velocity of this skydiver in a horizontal position.
The density of air is 1.21 kg/m^3 drag coefficient C skydiver horizontal = 1.0. The skydiver deploys his parachute. It has a frontal area of 24 m^2 and a drag coefficient of 1.5 .
Calculate the terminal velocity once the parachute is deployed.
