Best ResponseYou've already chosen the best response.1W = 4j = 0i + 4j Anything of the form W = ai + bj has the magnitude W = sqrt(a^2 + b^2) The unit vector of W will be (1/W)*W this vector will be of length 1 and it will point in the same direction as W

Best ResponseYou've already chosen the best response.1do you see how 0i + 4j matches up with ai + bj making a = 0 b = 4
