A skydiver of mass m = 70 kg, which includes the mass of all the equipment she is wearing (helmet, parachute, etc.), jumps from an airplane at high altitude. The density of the air is ρ = 1.22 kg/m3 .

(a) Estimate a numerical value for the terminal speed of the diver while she is in a horizontal spread-eagle formation. (Parachute is not open.) The drag coefficient of the diver in this formation is about 1.0. Any other needed quantities should be estimated. Show your starting formulas and all your work.

(b) Estimate a numerical value for the terminal speed of the diver while she is in a head first vertical dive. (Parachute is not open.) The drag coefficient of the diver in this formation is about 0.70. Any other needed quantities should be estimated. Show your starting formulas and all your work.

(c) Estimate a numerical value for the terminal speed of the diver when her parachute is open. The drag coefficient of the diver in this formation is about 1.75. Any other needed quantities should be estimated. Show your starting formulas and all your work.
