CASE STUDY 1 1. A plane takes off from a level runway with two gliders in tow, one behind the other. The first glider has a mass of 1600 kg and the second a mass of 800 kg. The frictional drag may be assumed as constant and equal to 2000 N on each glider. The towrope between the first glider and the plane can withstand a tension of 10 000 N. (a) If a velocity of 40 m/s is required for takeoff, how long a runway is needed? (b) How strong must the towrope between the two g
