Academics

A skydiver weighing lb (including equipment) falls vertically downward from an altitude of ft and opens the parachute after s of free fall. Assume that the force of air resistance is when the parachute is closed and when the parachute is open, where the velocity is measured in ft/s.

Use ft/s2. Round your answers to two decimal places.

(a) Find the speed of the skydiver when the parachute opens.

(b) Find the distance fallen before the parachute opens.
