Jul 29	accepted	What method should I use to solve for the final acceleration of a projectile being launched from the earth's surface?
Jul 28	comment	What method should I use to solve for the final acceleration of a projectile being launched from the earth's surface? Ok. What I am confused about now is how is $F = {GMm}/{r^2}$ going to help me if the unknowns in your equation are $m$ and $v_f$. I can solve for $v_f$, but $m$ is what I need to plug into $F = {GMm}/{r^2}$, right? So how do I solve for $m$ when it has been factored out of the equation?
Jul 28	comment	What method should I use to solve for the final acceleration of a projectile being launched from the earth's surface? You were right. I neglected to specify that the question does include $d$, the distance from the surface of the earth.

Jul 25	comment	If you have three masses in a line, determine the position of the middle masses given that the net force of the gravitational force is 0 MGZero, was I correct in my above comment?
Jul 25	comment	If you have three masses in a line, determine the position of the middle masses given that the net force of the gravitational force is 0 Ted, you are correct. I neglected to square the distance. Shouldn't the formula be: $$F = \frac{GMm_3}{(r_2)^2} - \frac{Gmm_3}{(d-r_2)^2}.$$
