An object is moving counterclockwise at a constant speed around the circle x^2 + y^2 = 1, where x and y are measured in meters. It completes one revolution every minute.

a) What is its speed?

b) What is its velocity vector 30 seconds after it passes the point (1,0)? Does your answer change if the object is moving clockwise? Explain.
