A transport plane takes off from a level landing field with two gliders in tow, one behind the other. The mass of each glider is 700 , and the total resistance (air drag plus friction with the runway) on each may be assumed constant and equal to 2600 . The tension in the towrope between the transport plane and the first glider is not to exceed 12000 .
a.) find the minimum length of the runway, if a speed of 40m/s is needed to takeoff.
b.)tension between 2 gliders while they are accelerating for takeoff
