Meriam, Kraige & Bolton — Kinetics of Particles: Problem 3_273

3/273 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°, 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.
