[QUOTE="Alameen Damer, post: 5220163, member: 566472"] What I did was: Let mE be mass of Earth Let mM be mass of the moon Let mR be mass of the rocket GmEmR/r^2=GmMmR/(3.8x10^8-r)^2 (3.8x10^8-r)^2(GmEmR)=r^2(GmMmR) G and MR cancel (3.8x10^8-r)^2(mE)=r^2(mM) (5.926x10^24)r^2-4.56x10^34r+8.664x10^41=0 I then used the quadratic formula to solve for r, getting 342017105.1 m. This is the radius from the Earth to the rocket to distance from the moon to the rocket would be: 3.8x10^8m-342017105.1 m=3.8x10^7m. HOWEVER, i am wondering is there an easier approach to solving this? [/QUOTE]
