(a) A plane is traveling due east and passes over a radar station. When the plane is directly over the station, the building and the plane are 3 miles apart. If the angle shown below is changing at a rate of 0.04 rad/s, at what rate is the distance r between the plane and the radar station changing when e = 0.25 radians? Express your answer in units of miles/hour, to three decimal places. ... 3 mi mi/hr (h) What je the eneed of the nlane (in milec/hour). at this moment? Exnr answ to three significant digits
