Problem: A rope runs from a hook at A (0, 0, 3) m to a point B (5, 2, 0) m on the floor (\(xy\) plane). Find the angle between the rope and the floor. Hint: the angle with a plane is \(90^\circ\) minus the angle with its normal.
What this problem relies on
Use the dot product to find the angle between two lines and the parallel and perpendicular components of a force.
Write a cable or rope force as a Cartesian vector from the coordinates of two points, using position and unit vectors.
