For example, an upward 5 kN load (force vector) applied to the tip of an airplane wing gives rise to quite a different stress and deflection pattern in the wing than the same load acting at the wing’s mid-span

On a NASA mission the space shuttle Atlantis orbiter was reported to weigh 239,255 lb just prior to lift off.
On orbit 18 at an altitude of about 350 km, the orbiter’s weight was reported to be 236,900 lb. (a) What was
the mass, in kilograms, of Atlantis on the launch pad and in orbit? (b) If no mass were lost between launch
and orbit 18, what would have been the weight of Atlantis, in pounds?

Show that in the absence of an atmosphere, the shape of a low altitude ballistic trajectory is a parabola.
Assume the acceleration of gravity g is constant and neglect the earth’s curvature.
