1. The problem statement, all variables and given/known data I got this problem: A wedge of mass m = 36.1 kg is held in place on a fixed plane that is inclined by an angle θ = 21.3° with respect to the horizontal. A force F = 302.3 N in the horizontal direction pushes on the wedge, as shown in Figure 4.25a. The coefficient of kinetic friction between the wedge and the plane is μk = 0.159. Assume that the coefficient of static friction is low enough that the net force will move the wedge. http://semmedia.mhhe.com/physics/bau...dge/index.html basically what's there except friction would be the other way around (since its accelerating up the slide. 2. Relevant equations FBD Sum of all forces = ma 3. The attempt at a solution I did a free body diagram and got: Summation of forces in y: Normal force = mg sin theta + Appliedforce sin theta Then for the forces in x: mgcos + friction - Aplliedforce sin = 36.1a I did solve for everything but strangely the acceleration gives me acceleration = 3.2 Can any1 help me if im doing something wrong? Like getting cos and sin mixed?
