Resisted motion is a relatively common feature of HSC mechanics questions, be they in a straight line, or projectile motion questions. The important point is to use Newton's Second Law, $$\sum F=m\ddot{x}$$ Make sure you always define you directions at the start!

Extension II Mechanics Syllabus
Here is an interactive form for you to check off each part of the syllabus as we work through mechanics.
There seems to be a lot here, but don't let it put you off! Most the of mechanics hinges on the ability to write components of vectors and make sure the signs are correct.
