3. The drag force of an object moving through a fluid is found to be F₁ = CpAv² where C the drag coefficient, A is the area of the object facing the fluid, and p is the density of th fluid. The drag coefficient is determined experimentally. Using this form of the drag forc calculate the terminal velocity of a 75 kg skydiver in 2 positions: diving head first like an arrow (C=0.70, A=0.18 m²) and laying horizontal (C=1.0, A=2 m² ). The density of air is p = 1.21 kg/m³.
