Once you have that basic understanding then you can simply find the components and solve the problem. He has videos describing the parallelogram in his kinematics playlist if you need to use it.

    btw no hyperbole here, but def the best educational (key word educational, not to be confused with edutainment...al?) channel on youtube! i do have one question though for anyone who cares to answer. how come the acceleration associated with the weight force is not affected when an object is raised or lowered?
