Having aced your introductory physics course, you are hired as a summer intern at NASA. You are sent as part of a team to explore the possibility of mining iron from a small, airless spherical asteroid with a radius of 471 km and a surface acceleration of 3.4 m/sec2. 1) What is the mass of the asteroid? kg Submit 2) What is the minimum vertical velocity you could give a 3 kg rock from the surface of this asteroid so that it continues to move upwards forever (f.e. it would never return to the surface)? m/sec Submit 3) What is the minimum vertical velocity you could give a 6 kg rock from the surface of this asterold so that it continues to move upwards forever (1.e. it would never return to the surface)? m/sec Submit 4) How far will the 3 kg rock go if it leaves the asteroids surface with a vertical velocity of 1000 m/sec?"; m Submit 5) What will the speed of the 6 kg rock be at the surface of the asteroid if it is dropped from a point 1000km above the surface of the asteroid? m/sec Submit
