A boat man could row his boat with a speed 10 m/sec. He wants to take his boat from P to a point Q just opposite on the other bank of the river flowing at a speed 4 m/sec. He should row his boat–

Water is flowing in a river of width 36m with a speed of 2ms^(-1) .A person in a boat at a point "P" on the bank of the river wants to cross the river by the shortest path to reach a point "Q" directly opposite on the other bank.If he can row his boat with a speed of 4ms^(-1) in still water,he should row his boat at an angle of ?

A river is flowing steradily with a speed 5 km h^(-1) . A boat man can row with a speed of 10 km h^(-1) in still water. He rows his boat in river at right angles to the bank of river, If width of river is 800 m , (i) how much time the boat man will take to cross the river ? (ii) How far away from a point just opposite to the bank of river he will be reaching there ? (ii) What will be his effective speed gt

A boat is travelling on a river with a speed of 3m/sec. The force on the boat by water is 500N. The power delivered by the engine of the boat is :

A boat man can row with a speed of 10 km/hr. in still water. The river flow steadily at 5 km/hr. and the width of the river is 2 km. if the boat man cross the river with reference to minimum distance of approach then time elapsed in rowing the boat will be:-

A boat man can row with a speed of 10 km/hr. in still water. The river flow steadily at 5 km/hr. and the width of the river is 2 km. if the boat man cross the river with reference to minimum distance of approach then time elapsed in rowing the boat will be:-

A boat man can row with a speed of 10km/hr in still water.The river flow steadily at 5km/hr and the width of the river is 2km. If the boat man cross the river with reference to minimum distance of approach then time elapsed in rowing the boat will be

A boat man can row with a speed of 10 km/hr. in still water. The river flow steadily at 5 km/hr. and the width of the river is 2 km. if the boat man cross the river with reference to minimum distance of approach then time elapsed in rowing the boat will be:-

A motor boat is travelling with a speed of 3.0m / sec . If the force on it due to water flow is 500 N , the power of the boat is
