Consider a body falling through the air. The force due to air resistance is given by, F(air)=CAv^2, where C is the coefficient of air friction, A is the area facing the direction of the motion, and V is the velocity of the object with respect to the air. Take the value, C=0.88kgm^-3. If a body falls sufficiently far it will reach its terminalVelocityt, vt. ind this terminal velocity. in miles per hour, for a body of mass 70 kg and effective area of 0.2m^2.
