Here are the problems. I have no idea where to start! I don't want the answer I just want a little clue to get me started.

If someone could just explain to me the steps I should take to go about solving these problems. BTW, I am clueless about the formulas. I only know Force = mass*accelaration.

The typical approach for dealing with problems like these is to start by drawing a free body diagram.
Once you have a free body diagram, you can figure out expressions for the net force on the object that you're interested in.
Using the expression for net force, you can apply F=ma.
