Task id12596
A raft is anchored on a river at a distance L=60 m from the shore. The speed u of the river current near the shore is zero and increases in proportion to the distance from the shore, so that for the raft it is equal to uL = 2 m/sec. The motor boat departs from the shore towards the raft. Relative to the water, the boat develops a speed v = 7.2 km/h. How should the motorman orient the boat before departure so that, without further adjustment of the speed of the boat, he will land on the raft exactly opposite the place of departure? How long will the boat be on its way?
