PLEASE PLEASE HELP!!! : 14. Archimedes is supposed to have said, “Give me a place to stand on and I will move the Earth.” Suppose you had an object with a mass equal to that of Earth—5.98 × 10^24 kg—and that it experienced gravity equal to that at Earth’s surface, so that its weight was 5.87 × 10^25 N. If by using a lever you could move this mass with a force of 175 N, what would be the mechanical advantage of the lever?

    15. Suppose the fulcrum of the lever in problem (14) is placed 1.00 m away from the mass. How far from the fulcrum would you have to be (what would the input distance be) in order for the lever to have the mechanical advantage you calculated in problem (14)? (Note: the nearest galaxy to ours, the Andromeda Nebula, is 2 million light years, or 1.9 × 1022^m, away.)
