1. At a distance of 25km from the eye of a hurricane, the wind is moving at 180km/h in a circle. What is the magnitude of the centripetal acceleration, in meters per second squared, of the particles that make up the wind? 2. Relevant equations Ac=V^2/r = 4∏^2r/T^2 = 4∏^2rf^2 3. The attempt at a solution Ac=V^2/r The answer is 0.10m/s but I just cant seem to get it right.
