2. To move a large crate of mass 32.0 kg across a rough floor, with coefficient of kinetic friction between the crate and the floor is = 0.45, you pull on it with a Force P at an angle of 30° above the horizontal and some else also pushes on the crate with a force F at an angle 45° below the horizontal. (The applied forces, F & P, on the crate starts it moving.) (a) Find the Normal force acting on the crate. (b) Find the acceleration of the crate if the applied force is F = 130 N & P = 300 N. Sketch and Label all the forces Define the coordinate axis for each mass. F P
