(C) 13.40 m/s and 12694.1 N (D) 12.94 m/s and 13146.0 N
A glider having a mass of 500 kg is taken to an a ltitude of 1000 m with a jeep moving on ground at
54 kmph. Upon reaching the required altitude in 50 s, the glider is released and starts its descent.
Under the assumption of equilibrium glide, the range and endurance of the glider for a constant lift-
to-drag ratio of 15 are
