Current Attempt in Progress
- A star of mass \( 6 \times 10^{30} \mathrm{~kg} \) is located at \( <7 \times 10^{12}, 4 \times 10^{12}, \mathrm{O}>\mathrm{m} \). A planet of mass \( 4 \times 10^{24} \mathrm{~kg} \) is located at \( <5 \times 10^{12}, 6 \times 10^{12}, 0>\mathrm{m} \) and is moving with a velocity of \( <1.5 \times 10^{4}, 1.6 \times 10^{4}, 0>\mathrm{m} / \mathrm{s} \).
Part 1
(a) During a time interval of \( 1 \times 10^{6} \) seconds, what is the change in the planet's velocity?
\[
\vec{v}_{f}-\vec{v}_{i}=<
\]
