The 150-kg glider B is being towed by airplane A, which is flying horizontally with a constant speed of v = 218 km/h. The tow cable has a length r = 51 m and may be assumed to form a straight line. The glider is gaining altitude and when θ reaches 16°, the angle is increasing at the constant rate = 3 deg/s. At the same time the tension in the tow cable is 1235 N for this position. Calculate the ff:
a. the magnitude of the acceleration of glider B.
b. aerodynamic lift L and drag D acting on the glider.

The 89-kg man dives from the 45-kg canoe. The velocity indicated in the figure is that of the man relative to the canoe just after loss of
contact. If the man, woman, and canoe are initially at rest, determine the horizontal component of the absolute velocity of the canoe
(positive if to the right, negative if to the left) just after separation. Neglect drag on the canoe, and assume that the 67-kg woman
remains motionless relative to the canoe.
