Two long motor boats are moving in the same direction in still water, the boat A with speed of 10km/h and other with a speed of 20km/h. While they are passing each other coal is shoveled from the slower boat to the faster one at a rate 1000kg/min. Assume that the shoveling is always normal relative to the boat A and resistance offered by water is negligible. How much approximate additional force must be provided by driving engine of faster boat (B) if its velocity is to be maintained constant
