Transcribed Image Text: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 lengthr = 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 ở = 3 deg/s. At the same time the tension in the tow cable is 1550 N for this position. Calculate the
aerodynamic lift Land drag D acting on the glider.
