Beth is studying a rotating flow in a wind tunnel. She measures the u and ? components of velocity using a hot-wire anemometer. At x = 0.40 m and y = 0.20 m, u = 10.3 m/s and ? = −5.6 m/s. Unfortunately, the data analysis program requires input in cylindrical coordinates (r, ?) and (ur, u?). Help Beth transform her data into cylindrical coordinates. Specifically, calculate r, ?, ur, and u? at the given data point
