The earth takes one year to orbit the sun at a distance of 1.5*10^11m. Calculate it's speed. Explain why this is it's average speed and not it's velocity.
Can someone explain this plzzzzzzzz

maybe cuz it comes back to its original position after a complete round and displacement (in the case of velocity) becomes zero.
i think so

I think Silent Hunter is right cuz' I thought so 2. :)
During an orbit, the earth returns to its original position, which makes displacement 0. There no displacement ---> no velocity.

An aircraft is used on a short horizontal flight on its journey from A to B the resultant velocity of the aircraft is 15m/s in a direction 60 degrees east of north and the wind velocity is 7.5m/s due north.
Show that for the aircraft to travel from A to B it should be pointed due east.
