A force of 50 pounds is directed 30 from the horizontal, find the vector that represents this force.
bekas [8.4K]
I assume it is directed 30 degrees above the positive x-axis. F = 50 pounds F_x = 50 cos(30) pounds = 43.3 pounds F_y = 50 sin(30) = 25 pounds Let i and j be unit vectors along the x and y axes, respectively.  Then F = F_x i + F_y j = (43.3 i + 25 j) pounds
