A boat moves relative to water with a velocity `v` which is `n` times less than the river flow velocity `u`. At what angle to the stream direction must the boat move to minimize drifting ?

A boat moves relative to water with a velocity which is n=2.0 times less than the river flow velocity. At what angle to the stream direction must the boat move to minimize drifting?

A boat moves in still water with a velocity which is k xx less than the river flow velocity.Find the angle to the stream direction at which the boat should be rowed to minimize drifting.

A boat moves relative to water with a velocity v and river is flowing with 2v. At what angle the boat shall move with the stream to have minimum drift?

A man can row a boat in still water with a velocity of 8 kmph .Water is flowing in a river with a velocity of 4 kmph . At what angle should he row the boat so as to reach the exact opposite point

The velocity of boat relative to water is 4 m/sec . The velocity of water relative to ground is 8m/sec . In what direction boatman aims the boat to cross the river in minimum drift distance method.

A boat stems in a river with velocity 2hati + hatj with respecitve to the ground. The river water flows with a velocity -3hati - 4hatj with respect to the ground. What is the relative velocity of boat w.r.t river water ?

A boat is moving with a velocity 2i + 3j with respect to ground. The water in the river is moving with a velocity -2i - 3j with respect to ground. The relative velocity of the boat with respect to water is

Show that the direction of the shortest route is at right angles to the river when the velocity of the swimmer is greater than that of the river. Show also that when the velocity of the swimmer is less than that of the river, the direction is tan^(-1)v//sqrt(u^(2)-v^(2)) where v= velocity of swimmer and u= velocity of river.
