1. The problem statement, all variables and given/known data Fred's friends are in a boat. If they could travel perpendicularly to the shore, they could land at his position. However, a strong current vc is greater than the maximum vm of the motor. Find the magnitude of the angle, measured relative to the straight-across direction, at which his friends should point the boat to minimize the distance Fred has to walk. a) arcsin (vm/vc) b) arctan (vc/vm) c) tan (vc/vm) d) arctan (sqrt(vc/vm)) 2. Relevant equations a^2 + b^2 = c^2 sin(theta) = opposite/hypotenuse (=> theta = arcsin(opposite/hypotenuse)) cos(theta) = adjacent/hypotenuse tan(theta) = opposite/adjacent vx = vcos(theta) vy = vsin(theta) v = vx+vy 3. The attempt at a solution I tried to draw this out and I get that the angle is represented by theta = arctan(vm/vc). I don't know what I'm doing wrong, please help!
