An aircraft carrier is transiting out to sea with acceleration ag = -1 m/s² and speed VG = -5 m/s (i.e., both to the left) when its onboard radar detects a UFO. At the instant shown, the radar is pointed at angle = π/4, has angular velocity = 0.5 rad/s (CCW), and has angular acceleration α = 0.02 rad/s² (CCW). The radar uses a body reference frame that is moving and rotating with the radar: B = {O', 6₁, 62, 63} to report measurements. The radar reports the relative position (x, y) = (100, 150) meters in the radar's body frame along with the body-frame velocities (x, y) = (Vx, Vy) = (-30, 30) m/s a body-frame acceleration (x, y) = (ax, ay) = (0.1,0.3) m/s² of the UFO. 1. Determine the inertial velocity vector of the UFO expressed in terms of unit vectors of the inertial frame I = {0, 11, 12, 13} located at the base. 2.
