First I used Newtons gravitational force equation. Fg= GM1M2/r^2
M1=5E30 kg is given
M2 = 3.5E30 kg is given
G = 6.66E11
Calculated R by using pythagorean theory for both coordinates and adding together
I got R =1.14E13
Then using the force calculated I used the momentum principle, delta p = Fnet delta t
