A boat moves in still water with a velocity which is `k` times 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 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 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 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

A boat crosses a river with a velocity of 8(km)/(h) . If the resulting velocity of boat is 10(km)/(h) then the velocity of river water is

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 ,man wishing to cross a river flowing with velocity u jumps at an angle theta with the river flow. (a) Find the net velocity of the man with respect to ground if he can swim with speed v in still water. (b) In what direction does the boat actually move ? ( c) Find how far from the point directly opposite to the starting point does the boat reach the opposite bank, if the width of the river is d .

The river 500 m wide is flowing with a current of 4kph. A boat starts from one bank of the river wishes to cross the river at right angle to stream direction. Boatman can row the boat at 8 kph. In which direction he should row the boat. What time he ''ll take to cross the river ?
