An astronaut is inside a 2.25 * 106 kg rocket that is blasting off vertically from the launch pad. You want this rocket to reach the speed of sound 1331 m/s2 as quickly as possible, but astronauts are in danger of blacking out at an acceleration greater than 4g. (a) What is the maximum initial thrust this rocket’s engines can have but just barely avoid blackout? Start with a free-body diagram of the rocket. (b) What force, in terms of the astronaut’s weight w, does the rocket exert on her? Start with a free-body diagram of the astronaut. (c) What is the shortest time it can take the rocket to reach the speed of sound?

Question
An astronaut is inside a 2.25 * 106 kg rocket
that is blasting off vertically from the launch pad. You want this rocket
to reach the speed of sound 1331 m/s2 as quickly as possible, but astronauts
are in danger of blacking out at an acceleration greater than 4g.
(a) What is the maximum initial thrust this rocket’s engines can have but
just barely avoid blackout? Start with a free-body diagram of the rocket.
(b) What force, in terms of the astronaut’s weight w, does the rocket
exert on her? Start with a free-body diagram of the astronaut. (c) What is
the shortest time it can take the rocket to reach the speed of sound?
