Question

A particle moves at constant speed in a circular path, centered about the origin, such that w = 1.7 rad/s. At some instant, its position is (x,y) = (3.39, 0.63)

What is the radius of the circle?
How does your answer change if w = 3.4 rad/s?

Answer 1

if the center is at the origin it is always the same distance from the origin.
R = sqrt (x^2 + y^2)
