i. A ship, sailing due North at speed u, drops a weight ofmass m into the sea every four minutes. A second ship, sailing 60 ° North of East at speed 2u/3, drops a similar weight every six minutes. If the second ship starts at 30km West of the first, devise an expression for the distance between the closest two weights once they reach the seabed. Assume a uniform depth at all points.
