A transport plane takes off from a level landing field with twogliders in tow, one behind the other. The mass of each glider is700 kg, and the total resistance (air drag plus friction with therunway) on each may be assumed constant and equal to 2500 N. Thetension in the towrope between the transport plane and the firstglider is not to exceed 12000 N.
-If a speed of 40 m/s is required for takeoff, what minimum lengthof runway is needed?
-What is the tension in the towrope between the two gliders whilethey are accelerating for the takeoff?
