Best ResponseYou've already chosen the best response.0yeah ..and if lower velocity , down ?

anonymous

Best ResponseYou've already chosen the best response.0Yeah that will depend upon velocity of water..

Best ResponseYou've already chosen the best response.0Have you studied about the formula: \[Resultant (R)= \sqrt{A^2 + B^2 + 2AB \cos(\theta)}\]

anonymous

Best ResponseYou've already chosen the best response.0Here 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 ??

anonymous

Best ResponseYou've already chosen the best response.0yeah .. how do we find theta ?

anonymous

Best ResponseYou've already chosen the best response.0Theta 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 ??
