A certain parachute has a drag coefficient of C D = 1.5. If the parachute and skydiver
Question:
A certain parachute has a drag coefficient of CD = 1.5. If the parachute and skydiver together weigh 225 lb, what should the frontal area of the parachute be so that the skydiver’s terminal velocity is 15 mph when approaching the ground? Is it reasonable to neglect the buoyant force that is present?
