1. The problem statement, all variables and given/known data The surface of an inclined plane shown below is frictionless. if F= 29N, what is the magnitude of the force exrted on the 3.0-kg by the 1.8kg block? 2. Relevant equations I suppose F=MA 3. The attempt at a solution I'm utterly confused here. The equation I have for force doesn't factor in angles, there may be a variation of the force equation that I do not know of. I don't have the acceleration of block 3.0kg needed to find the force using the information given. I'm assuming it'd be acceleration due to gravity at an angle perpendicular to the inclined plane but I'm not sure.
