This was somewhat helpful, but my radius is not 3.5km it's 5km. This is not the answer to my question, it is only similar to it. I can not interpret your handwriting to follow along to answer for my question.
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.

Thank you, how would you calculate #3.
Is it wrong to say count to the right of the decimal point to get 10^-5 for the below? Please explain, as I am a bit confused with the 10^-5, as I think to the left because of the negative. 0.000036 s = 3.60 * 10^-5 s
