The 200-kg glider B is being towed by airplane A, which is flying horizontally with a constant speed of v = 194 km/h. The tow cable has a length r= 59 m and may be assumed to form a straight line. The glider is gaining altitude and when e reaches 16°, the angle is increasing at the constant rate = 3 deg/s. At the same time the tension in the tow cable is 1550 N for this position. Calculate the aerodynamic lift L and drag D acting on the glider. Assume o = 12°. B A
