Among other things, the angular speed of a rotating vortex (such as in a tornado) may be determined by the use of Doppler weather radar. A Doppler weather radar station is broadcasting pulses of adio waves at a frequency of 2.85 GHz, and it is raining northeast of the station. The station receives a pulse reflected off raindrops, with the following properties: the return pulse comes at a bearing of 51.4° north of east; it returns 180 us after it is emitted; and its frequency is shifted upward by 214 Hz. The station also receives a pulse reflected off raindrops at a bearing of 52.3° north of east, ofter the same time delay, and with a frequency shifted downward by 214 Hz. These reflected pulses have the highest and lowest frequencies the station receives. (a) Determine the radial-velocity component of the raindrops (in m/s) for each bearing (take the outward direction to be positive). 51.4° north of east m/s 52.3° north of east m/s
