Suppose I am on ISS and earth is exactly below (at the right angle to the ISS's line of path). Now if I throw one ball below towards earth from window at exactly 90 degrees to the line of path of ISS and one ball upwards at right angle to the line of path of ISS. **Assume normal human strength for throwing ball. Say @ 50km/hr 1. Will first ball continue to travel "downwards" (as seen from ISS) and eventually enter into earth's atmosphere and burn out (or reach earth...whatever) 2. Will second ball contunue to travel "upwards" (as seen from ISS) and will escape the earth's pull ?
