Chapter 3, Problem 3/334(choose chapter or problem)
The 200-kg glider B is being towed by airplane A, which is flying horizontally with a constant speed of 220 km / h. The tow cable has a length r = 60 m and may be assumed to form a straight line. The glider is gaining altitude and when \(\theta\) reaches \(15^{\circ}\), the angle is increasing at the constant rate \(\dot{\theta}=5\) deg/s. At the same time the tension in the tow cable is 1520 N for this position. Calculate the aerodynamic lift L and drag D acting on the glider.
