MOTION OF A BOAT IN A RIVER
Motion in Plane

269955 The velocity of water in a river is \(2 \mathbf{k m p h}\), while width is \(400 \mathrm{~m}\). A boat is rowed from a point rowing always aiming opposite point at \(8 \mathrm{kmph}\) of still water velocity. On reaching the opposite bank the drift obtained is

1 \(93 \mathrm{~m}\)
2 \(100.8 \mathrm{~m}\)
3 \(112.4 \mathrm{~m}\)
4 \(100 \mathrm{~m}\)
Motion in Plane

269994 A boat takes\(4 \mathrm{hr}\) upstream and \(2 \mathrm{hr}\) down the stream for covering the same distance.The ratio of velocity of boat to the water in river is.

1 \(1: 3\)
2 \(3: 1\)
3 \(1: \sqrt{3}\)
4 \(\sqrt{3}: 1\)
Motion in Plane

269995 The width of a river is\(2 \sqrt{3} \mathrm{~km}\). A boat is rowed in direction perpendicular to the banks of river. If the drift of the boat due to flow is 2 \(\mathbf{k m}\), the displacement of the boat is.

1 \(3 \mathrm{~km}\)
2 \(6 \mathrm{~km}\)
3 \(5 \mathrm{~km}\)
4 \(4 \mathrm{~km}\)

269996 Person aiming to reach the exactly opposite point on the bank of a stream is swimming with a speed of\(0.5 \mathrm{~ms}^{-1}\) at an angle of \(120^{\circ}\) with the direction of flow of water. The speed of water in the stream is

1 \(1 \mathrm{~ms}^{-1}\)
2 \(0.25 \mathrm{~ms}^{-1}\)
3 \(0.67 \mathrm{~ms}^{-1}\)
