i want to use F=G(m1m2)/r^2=m1a so Gm2/r^2=a

6.67x10^-11*607/(1.71/2)^2=a

then when i have a i am going to use x=xo+vot+.5at^2 to find t

i am not getting the right answer please help me

Actually, I think I will stick with my original advice. Like I said, you shouldn't be dividing the distance by 2. If the force is constant, I would think you take it at the 1.71 m.

At a blush. I think the decision to halve the 171 is mistaken

well the problem tells you to use 170,

so we have :

f=6.67E-11*607*2.2/.170^2=?

Divide by 2.2 to get a, then use kinematics

PS oops thats meant to be 1.7
