The low cable has a length r = 60 m and may be assumed to form a straight line. The glider is gaining altitude and when θ reaches 15°, the angle is increasing at the constant rate θ•=5 deg/s. At the same time the tension in the tow cable is 1520 N for this position. Please calculate the aerodynamic lift L and drag D acting on the glider. (20%)
