Social ScienceA wheel is mounted on a stationary axle that lies along the z axis. The center of the wheel is at <0, 0, 0> m. It is rotating with a constant angular speed of 31 rad/s. At time t = 4.40 s a red dot painted on the rim of the wheel is located at <0.20, 0, 0> m. At time t = 4.48 s, what is the location of the red dot? (Assume that the wheel rotates in the counterclockwise direction. Express your answer in vector form.)
