i don't know how to find the acceleration in a frictionless inclined plane

Look at the diagram. Since we are on a frictionless incline, the**only**force acting on the blue object**along**the incline is the component of the force of gravity ($\displaystyle F_g$) parallel to it, i.e. $\displaystyle mg\sin \theta$).

So, the net force acting on the object along the incline is given by: $\displaystyle F_{\text{net}} = mg \sin \theta$

But what do we know about $\displaystyle F_{\text{net}}$ ? Newton's second law! - Jan 7th 2009, 03:11 AMmr fantastic
Do you have any experience solving these sorts of problems?

You can do the experiments at this website:

CalcTool: Object on a slope calculator

Give M different values and see what happens to the acceleration.
