Two beetles run across flat sand, starting at the same point. Beetle 1 runs 0.50 m due east, then 0.71 m at 390 north of due east. Beetle 2 also makes two runs; the first is 1.44 m at 36" east of due north. What must be (a) the magnitude and (b) the direction (relative to the cast direction in the range of (-180 180")) of its second run if it is to end up at the new location of beetle 1?
