Water traveling along a straight portion of a river normally flows fastest in the middle, and the speed slows to almost zero at the banks. consider a long stretch of river flowing north, with parallel banks 40 m apart. if the maximum water speed is 3 m/s, a reasonable model for the water speed of a river x units from the west bank is a sine function: f(x) = 3 sin (Ï€x/40).if a boater would like to cross theriver from a point on the west bank and land at a point exactly opposite with constant headin and a constant speed of 5 m/s, determine the angle at which the boat should head.
