1. The problem statement, all variables and given/known data Earth's orbit around the SUn is nearly circular. THe period is 1 year = 365.25 days. In an elapsed time of 2.70 days, what is earth's angular displacement? what is the change in earth's velocity (perpendicular to the average velocity) What is the earth's average acceleration during 2.7 days? (perpendicular to the average velocity) 2. Relevant equations a =v/t v = s/t 3. The attempt at a solution I have already completed the first question and got 4.64×10-2 rad and it was right. but the next two i'm having major problems with. and i am so confused. anyone help!
