An unidentified flying object (UFO) is being tracked by a radar tracking station A. It is moving in a level flight at altitudeh and a uniform speed and passes directly over the station. Attach an inertial frame of reference to the ground and assume a non-rotating Earth. Attach a non-inertial reference frame to the antenna with the x-axis always pointing from the antenna to the UFO (Please see figure below). The unit vectors in the inertial frame are given by I, J, K, while the unit vectors in the non-inertial frame are given byi,j,k. UFO (a) Express the unit vectors i,j,k in the non-inertial frame in terms of the unit vectors I, J, K in the inertial frame. (b) What is the velocity of the non-inertial frame with respect to the inertial frame?
