The speed of river current close to banks is nearly zero. The current speed increases linearly from the banks to become maximum `(= V_(0))` in the middle of the river. A boat has speed ‘u’ in still water. It starts from one bank and crosses the river. Its velocity relative to water is always kept perpendicular to the current. Find the distance through which the boat will get carried away by the current (along the direction of flow) while it crosses the river. Width of the river is l.

A boat moves perpendicular to the bank with a velocity of 7.2 km ph. The current carries it 150 m downstream. Find the velocity of current and the time required to cross the river.width of the river is 0.5 km.

The current velocity of river grows in proportion to the distance from its bank and reaches the maximum value v_0 in the middle. Near the banks the velocity is zero. A boat is moving along the river in such a manner that the boatman rows his boat always perpendicular to the current. The speed of the boat in still water is u. Find the distance through which the boat crossing the river will be carried away by the current, if the width of the river is c. Also determine the trajectory of the boat.
