An 85-kg skydiver fаlling in the heаd-first pоsitiоn initiаlly, but when they оpen their parachute, their cross-sectional area increases from 0.18 m2 to 22 m2. Assume the drag coefficient is 0.74 and the density of air, ρ = 1.22 kg/m3 at the altitude that the skydiver falls. What is the terminal velocity of the skydiver (in m/s) once the parachute has been opened fully?
