The terminal velocity of a person falling in air depends upon the weight and the area of the person facing the fluid. find the terminal velocity (in meters per second and kilometers per hour) of a 79.5 kg skydiver falling in a pike (headfirst) position with a surface area of 0.170 m2. (assume that the density of air is 1.21 kg/m3 and the drag coefficient of a skydiver in a pike position is 0.7.)
