A person in a rowboat crosses a river which flows with 2.147 km/hr. The person rows with maximum velocity of 6.835 km/hr relative to the water (measured while rowing on a still lake) and wants to reach the opposite shore directly across from the start point - along a line at 90 degrees with respect to the river shore . At what angle with respect to this line does the person have to point the boat (sheet 15 to 16")? Indicate with a negative (positive) sign whether the boat has to be pointed upstream (downstream).
The Attempt at a Solution
I'm not sure how to solve this, but i used the vector decomposition, 43.39 degree . . . i used the forumula [cos(data) = Ax/A]
Please anyone, help me out asap thank you so much...i need help urgently!!!
