I'm having trouble completing the problem I've attached a picture of below. I was able to find the the Earth's average speed in m/s relative to the sun by doing (2pi*(1.49x10^11))/31536000. But I am struggling to find the average velocity for the same thing over a period of one year in m/s. I was wondering how to calculate that? I've tried doing the (final velocity-initial velocity)/2 but the program doesn't accept my answer when using that approach.
A light year (LY) is the distance that light travels in one year.
1 LY = 9.46x1015 m.
Suppose we have detected a planet that orbits a star that is 104 light
years away. How many millions of years would it take us to get there if
we used a modern rocket with a maximum speed of 20.0 km/s (about
45,000 mph)? Assume 3 sig figs.

- The Earth has a mass of 5.97 * 1024 kg and the Sun has a mass of 2.00 * 1030 kg. If they are separated by a distance of 1.50 * 108km, what is the force (in N) between the Earth and the Sun?
