A river 60m wide is flowing at a rate of 4m/s .A boat is sailing at a velocity of 20 m/s with respect to the river in a direction making an angle `37^(@)` with the direction of river flow.Find time taken by the boat in seconds to reach the opposite bank. (A) 2 (B) 3 (C) `sqrt(6)` (D) 5

A river 500m wide is flowing at a rate of 4 m//s. A boat is sailing at a velocity of 10 m//s with respect to the water, in a direction perpendicular to the river. The time taken by the boat to reach the opposite bank

A river 400 m wide is flowing at a rate of 2.0 m//s. A boat is sailing at a velocity of 10.0 m//s with respect to the water In a direction perpendicular to the river. (a) Find the time taken by the boat to reach the opposite bank. (b) How far from the point directly opposite to the starting point does the boat reach the opposite bank?

A 400 - m wide river is flowing at a rate of 2.0 m s^-1 . A boat is sailing with a velocity of 10 m s^-1 with respect to the water, in a direction perpendicular to the river. (a) Find the time taken by the boat to reach the opposite bank. (b) How far from the point directly opposite to the starting point does the boat reach the opposite bank ? ( c) In what direction does the boat actually move ?

Velocity of the boat with respect to river is 10m/s. From point A it is steered in the direction shown. Where will it reach on the opposite bank ?

A river is flowing towards with a velocity of 5 m s^-1 . The boat velocity is 10 ms^-1 . The boat crosses the river by shortest path. Hence,

A swimmer wishes to cross a 500m wide river flowing at a rate 5km/hr. His speed with respect to water is 3km/hr. (a) If the heads in a direction making an angle theta with the flow, he takes to cross the river. (b) Find the shortest possible time to cross the river.

Velocity of the boat with respect to river is 10 m/s. From point A it is steered in the direction shown to reach point C. Find the time of the trip and distance between B and C

A river is 20 m wide. River speed is 3 m//s. A boat starts with velocity 2sqrt2 m//s at angle 45^@ from the river current (relative to river) (a) Find the time taken by the boat to reach the opposite bank. (b) How far from the point directly opposite to the starting point does the boat reach the opposite bank?
