The only force on the physicist is the downward force of gravity which in the physicist's case is about 638 N.The acceleration is just g downwards. The experience of  weightlessness is simply a proionged period with the total absence of gravitation field . We experience weight in everyday life via the presence of normal force and such.

The horizontal speed will remain constant  throught the flight. At the apogee,the velocity is at a minimum,there being no vertical speed is constrained to be 300km/hr,The KC-135 should enter the parabola as fast as possible to get the longest experimental time; this veiocity is 500mkm/hr. So,the angie ∝ satisfies cosα=300/500 and hence ,α=53
