A conveyor belt moves to the right with speed `upsilon = 300 m//s`. A very fast pieman puts pies on the belt at a rate of `20` per minute and they are recived at the other end by a pieeater.  (a) If the pieman is stationary find the spacing `x` betweenthe pies and the frequency with which they are recived by the stationary pieeater.  (b) the  pieman now walks with speed `30 n//min` towards the reciver while continuing to put pies on the recived by the stationary pieeater.
