4.1- how do we get an expression for the component of net force, F_net,x, in the x direction in terms of the variables in picture below

4.2- how do we get block's acceleration in x-direction, a_x, in m/s²

(13%) Problem 5: An object of mass m has these three forces acting on it (there is no normal force because it is not in contact with a surface). F1, F2, and F3 are shown in the gure. When answering the questions below. assume the w-direction is to the right, and the (gr-direction is straight ufwards. J\"! (13%) Problem 4: A block with a mass of m = 26 kg rests on a frictionless surface and is subject to two F forces acting on it. The rst force is directed in the negative xdirection with a magnitude of F l = I] N. The second has a magnitude of F 2 : 25' N and acts on the body at an angle 9 : J 90 measured from horizontal, as shown
