2 - 2500 cos 20 13. For a short time, the jet plane moves along a path in the shape of a lemniscate, r² = (2500cos 20) km². At the instant 0=30°, the radar tracking device is rotating at è =5(10³) rad/s with ë=2(10³) rad/s². Determine the components of the velocity and acceleration of the plane at this instant, a) in Cartesian Coordinates, b) in Normal and Tangential Coordinates, c) in Polar Coordinates. d) Also calculate the radius of curvature at the same instant.
