Homework Help: Physics

Posted by Anonymous on Tuesday, September 6, 2011 at 8:24pm.

Suppose a space capsule with an astronaut inside is launched from the top of a tower at some angle above the horizontal.
a)While the capsule is in free fall, what are the acceleration of the astronaut and the capsule?
b)If the astronaut measures his acceleration compared with that of the capsule, what value will he get?
c) In what sense can we say that the astronaut is "weightless" in the capsule? Is he "weightless" because the gravity of the earth has gone away?

This real confuses me so I greatly appreciate the help!
