QUESTION: A car goes around a circular track with a radius of 1000 m at a constant speed of 10 m/s.
(a) How long does it take the car to go once completely around the track?
(b) What is the average velocity of the car over this time interval?
WORK: What I did for (a) t= d/s (2pi(1000))/10= 628s
Final answer 6282
(b) average velocity v = s/(deltat) or v=deltax/ deltat
(2000-0)m/ 626s
Final answer 3.1847 m/s
Just want to know if this approach is the correct one

(a) looks good
part (b) may be a "trick" question
velocity is a vector quantity, while speed is a scalar
the answer might be zero
