Hello everyone, I have a physics test coming up and am working on the Pre-test however I have run into a problem and cannot find the proper equations anywhere to solve this... Box B has a mass of Mb=35.2kg and moves with a constant velocity along the x axis. The track has a friction coefficent of U(friction sign)k =0.320. draw a free body diagram and the four forces acting on it, Pulling force (Fp), Friction Force(Ff), Normal force (N) and finally Weight force (W). Also calculate the values of such forces. Ok I found out that Friction force = U(friction sign)*Normal force but I cannot find the equation to find weight force, normal force, or pulling force, What are they please? Im not asking for the solution to the problem just the equations used to solve it. Thanks for anyones time.
