Chapter 12.1, Problem 12.8P
A tugboat pulls a small barge through a harbor. The propeller thrust minus the drag produces a net thrust that varies linearly with speed. Knowing that the combined weight of the tug and barge is 3600 kN, determine (a) the time required to increase the speed from an initial value v1 = 1.0 m/s to a final value v2 = 2.5 m/s, (b) the distance traveled during this time interval.
