Question

Two stars interact with each other. Star 1 has a mass $2 \times 10^{30}$ kg, and Star 2 has a mass $1 \times 10^{30}$ kg. At a certain instant ($t = 0$), Star 1 is at the origin with zero velocity, and Star 2 is at ($-1.50 \times 10^{11}$, 0, 0) m with a velocity (0, $-3.50 \times 10^4$, 0) m/s. Later, at $t = 7.5 \times 10^6$ s, Star 1 has a velocity ($-1.20 \times 10^4$, $-1.69 \times 10^4$, 0) m/s. Define the system as Star 1 and Star 2. It is an isolated system, far from other stars.

Two stars interact with each other. Star 1 has a mass 2 imes 10^(30)kg, and Star 2 has a mass 1 imes 10^(30)kg. At a certain instant (t)=(0), Star 1 is at the origin with zero velocity, and Star 2 is at (:-1.50 imes 10^(11),0,0:)m with a velocity (:0,-3.50 imes 10^(4),0:)(m)/(s). Later, at t=7.5 imes 10^(6)s, Star 1 has a velocity (:-1.20 imes 10^(4),-1.69 imes 10^(4),0:)(m)/(s). Define the system as Star 1 and Star 2 . It is an isolated system, far from other stars a) what is the change un momenttum of start 1 during this time interval? b)what is the change in momentum of star 2 during this time interval? c)what is the momentum of star 2 at t=7.5*10^(6)? d)what is the velocity of Star 2 at t= 7.5*10^(6)? e) what us the momentum of the shstem at t= 7.5*10^(6)? Display answers in vector form system,far from other stars. 1 is at the origin with zero velocity, and Star 2 is at ( t = 7.5 109 s, Star 1 has a velocity (1.20 104, --1.69 104, 0) m/s. Define the system as Star 1 and Star 2. It is an isolated 1.50 1011, 0, 0) m with a velocity (0, - 3.50 104, 0) m/s. Later, at
