2. Make a kite that has a maximum lift force for a given wind speed and perimeter that does not exceed 70 cm. Consider the following: Lift force equation: L = C A. where C is lift coefficient (about 0.033), pis the density of air, v is the speed of wind and A is area of a kite. Keep in mind that density of air changes with temperature (this is a reasonable approximation for ordinary temperatures): p(T) = 1.3- 0.004AT, where p is in kg/m³, T is in °C and it is assumed that p(0) = 1.3 kg/m2. Meanwhile temperature depends on altitude: AT = -0.0035AH. What is the range of lift force for heights between 50 m and 200 m?
