2. If the rocket is to land on the surface of the planet,
determine the required free-flight speed it must have at A'
so that the landing occurs at B. How long does it take for the
rocket to land, in going from A' to B? The planet has no
atmosphere, and its mass is 0.6 times that of the earth.
Take G = 34.4(10 ")(lb • ft² )/slug², Mẹ = 409(10²') slug,
1 mi = 5280 ft.

The 245-kg glider Bis being towed by airplane A, which is flying horizontally with a constant speed of v = 183 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 14°, the angle is
increasing at the constant rate 0 = 8 deg/s. At the same time the tension in the tow cable is 2370 N for this position. Calculate the
aerodynamic lift L and drag D acting on the glider.
Assume o = 10°.
