How would I go about calculating the acceleration of a mass being pulled up an inclined plane at an angle.
Given - mass, and presumably angles

  1. Compute the net force along the direction of the plane, making sure to subtract friction (if any) and the component of weight along the plane (W sin A).

    Net force = mass x acceleration

    -That is the part that I don't get how to do...

  3. First, take the mass. It has weight mg. break that into components, normal to the plane, and down the plane.

    You I hope remember friction is dependent on the normal force.

    Pulling force-fd-friction=mass*a

    This problem is standard fore for physics test, make certain you can do these on your own.

  4. But what about the second angle? There is another one besides theta that I don't know what to do about - but that explanation just helped alot with all the other problems!

  5. on the angle of the rope pulling the object,you have to break that force into components: one is normal to the surface, that affects the normal force used in friction. Now the force parallel component is the pulling force. Sorry I did not see that at first.
