I think I've got it now.. Thank you soooooooooo much. I am failing physics so it was hard for me. Now l understand it better.

erm.. I think then its (.41kg)(9.81m/s^2)(sin21) which is 1.44N? So that's the applied force?

Isn't it fg=mg? So I drew an 8 cm line. And now I'm not sure how to continue. Do I draw the normal force? Is it (0.41kg)(9.81m/s^2)(cos21)?

Well I have the the diagram on a sheet of paper and it is much neater. I corrected the direction of the gravity arrow but I don't know how long it should be since it says that it must be scaled diagram in which 1N = 2cm.

I don't know how to use trig to find the forces and draw them? If that's what you meant... I'm sorry for being so dumb that I don't even know what I'm talking about.

The thing is, I don't know how to do that... Thank you though

Homework Statement For the maximum angle for which you have data draw a free body diagram and explain how the forces add to give the resultant (net) force and show the calculations required to determine the acceleration. The lab was about using Galileo's inclined plane to measure acceleration...
