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.

The velocity of a boat in still water is 10 m//s .If water flows in the river with a velocity of 6 m//s what is the difference in times taken to cross the river in the shortest path and the shortest time.The width of the river is 80 m .

. The velocity of a boat relative to water is represented by 3bar i +4bar j and that of water relative to the earth by bar i-3 bar j. What is the velocity of the boat relative to the earth, if bar i and bar j represent velocities of 1 km/hour east and north respectively .

Velocity of boat in still water is 13 m/s. If water flows ina river with a velocity of 5 m/s. What is the difference in times taken by him to cross the river in the shortest path and in the shortest time. If the width of the river is 10 m.

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?

What is the velocity at 4 sec, if velocity at = 0 is 8m/s

A river of width 100 m is flowing with a velocity of 1.5 m/s. A man start from one end with rest relative the river. He raws with an acceleration of 2 m//s^(2) relative to the river. If the man want to cross the river in minimum time, by how much distance (in meters) will he be drifted (flown) in the direction of river flow during the crossing.
