Suppose a force F is acting downwards on an object sitting on a plane that is inclined 45 degrees to horizontal. express the force as a sum of a force acting parallel to the plane and on acting perpendicular to the plane
I figured I need to use ||F||cos 45i+ ||F||sin 45j
and the angle between the plane and x-axis will the be the same angle between the downward and perpendicular
this is where I am getting stuck
