Best ResponseYou've already chosen the best response.1Now We have to find Resultant first.. For that we first make our figure look like parallelogram..

Best ResponseYou've already chosen the best response.1Since boat has higher velocity then boat will go in upward direction.. Getting ??

ashna

Best ResponseYou've already chosen the best response.1yeah ..and if lower velocity , down ?

waterineyes

Best ResponseYou've already chosen the best response.1Yeah that will depend upon velocity of water..

Best ResponseYou've already chosen the best response.1Have you studied about the formula: \[Resultant (R)= \sqrt{A^2 + B^2 + 2AB \cos(\theta)}\]

waterineyes

Best ResponseYou've already chosen the best response.1Here A is just velocity of boat that is : 25 and B is just velocity of water that is : 10 But you have to find theta first.. Right ??

ashna

Best ResponseYou've already chosen the best response.1yeah .. how do we find theta ?

waterineyes

Best ResponseYou've already chosen the best response.1Theta is basically angle between the two vectors A and B.. Here what is the angle between A and B.. Can you locate on the drawing ??

waterineyes

Best ResponseYou've already chosen the best response.1That is the angle between A and the resultant.. We have to locate angle between A and B..
