If you added enough ropes and pulleys to lift any size mass would it be possible to never have to apply a force to move your mass? Why or Why Not? Explain your answer using scientific terms we have been learning. pls help!!

The astronauts on the space shuttle flights experienced an acceleration of 29 m/s2 (about 3 "g's") during lift-off. what upward force must the astronaut's seat apply to the astronaut in order to cause this acceleration? assume the astronaut's mass is 70 kg, and compute this force when the acceleration is near the earth's surface so their weight equals latex: mg m g .
