A boat moving at 5 km/h to cross a river in which the current is flowing at 3km/h. in what direction should the boat head to reach a point on the other bank of the river directly opposite its starting point​?

Respuesta :

The boat will move in a direction that is 36.86 degrees away from the velocity vector as it attempts to reach the opposite bank from where it started.

We must understand the issue with the river crossing in order to identify the solution.

How can I determine the angle at which my boat should be travelling against the current to reach the other bank?

  • Let's assume that a boat traveling at velocity Vb is navigating a river with width d and flow Vr.
  • The boat's movement against the current to reach the opposite shore from its starting point will then be in the direction of,

                                   [tex]\alpha =sin^{-1}(\frac{V_R}{V_B} )[/tex]

  • First, using the provided information, we may create a flow diagram for this issue.
  • It is evident from the diagram that the angle will be,

                                       [tex]\alpha =sin{-1}(\frac{3}{5} )[/tex]

Thus, we can deduce that the boat will move in a direction that is 36.86 degrees away from the velocity vector as it attempts to reach the opposite bank from where it started.
