Stay Awake! 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 rockets engines can have but just barely avoid blackout? Start with a free-body diagram of the rocket. (b) What force, in terms of the astronauts 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?
● Overview of the Cosmological Argument: ○ While the ontological argument is a priori (independent of experience), the cosmological argument is a poste riori (takes personal experience into account). It claims that the observable world is ultimately explained by something transcendent: God. ○ Modal Terms: ■ Necessary thing: one whose nonexistence is impossible ■ Contingent thing: one whose existence a nd nonexistence are possible/impossible. ■ Possible thing: one whose existence is either certain or possible. ■ Impossible thing: one whose existence is impossible the opposite of a necessary thing. ■ Philosophe
