At t = 0 a star of mass 5.0×1030 kg has velocity < 6.0×10^4, 7.0×10^4, -7.0×10^4 > m/s and is located at < 1.00×10^12, -4.00×10^12, 4.00×10^12 > m relative to the center of a cluster of stars. There is only one nearby star that exerts a significant force on the first star. The mass of the second star is 3.5×10^30 kg, its velocity is < 1.0×10^4, -2.0×10^4, 9.0×10^4 > m/s, and this second star is located at < 1.04×10^12, -3.94×10^12, 3.96×10^12 > m relative to the center of the cluster of stars.
At t = 1.0×105 s, what is the approximate momentum of the first star? (in vector coordinates)
Was told to use Momentum principle, position update formula, and Newton's gravitational force law.
I keep on getting <3E35, 3.5E35, -3.5E35>kg m/s
The force of gravity I keep on calculating is not significant in that time to change the momentum of the particle.
