Question

Physics

Having aced your introductory physics course, you are hired as asummer intern at NASA. You are sent as part of a team to explorethe possibility of mining iron from a small, airless sphericalasteroid with a radius of 469 km and a surface acceleration of 3.4m/sec2.

4)How far will the 3 kg rock go if it leaves the asteroidssurface with a vertical velocity of 1000 m/sec?\"

(Not sure why the answer isn't 147059 m. I used vf^2 = vi^2 +2ah. 0 = 1000^2 + 2 * -3.4 m/s * h. h = (1000^2) / (2*3.4) = 147059m.)

5)What will the speed of the 6 kg rock be at the surface of theasteroid if it is dropped from a point 1000km above the surface ofthe asteroid?

(Not sure why the answer isn't 2608 m/s. I did v=sqrt(2ah) =sqrt(2*3.4*1000000).)
