What is the average linear speed of Mercury about the Sun? (The distance from the Sun to Mercury is 5.80 1010 meters. The orbital period around the Sun is 88 days.)
Divide 2 pi R by the period in days. The answer will be in meters per day. Divide than by 24x3600 = 86,400 sec/day to get V in meters per second.
