•
cos(θ) = b / (b^2+a^2)^(1/2) eq 3 Where (b^2+a^2)^(1/2) is the minimum distance the boat must travel, so gives minimum u
•
Now if we substitute eq 3and eq 1 back into eq 2
•
We get:
•
u = ab*v / b*(b^2+a^2)^(1/2)
•
Which cancels to give:
•
u = av / (b^2+a^2)^(1/2)
•
Which Isaac Physics had told me is the right answer
