please help me with this physics questions

Use the following five-step process to answer the calculation questions: 1. Draw a clearly labeled free-body diagram, with the coordinate system you are using indicated in the diagram. 2. Break each of the forces into their components. 3. Write out equations for the x- and y-components of the net force. 4. Write an expression relating the magnitude of the normal force to the magnitude of the friction force. 5. Combine your equations to find the answer(s) to the question. 1. A box with mass m is dragged across a level floor with coefficient of kinetic friction /4 by a rope that is pulled upward at an angle @above the horizontal with a force of magnitude F. In terms of the variables given, write an expression for the mass of the box needed so that it moves across the floor at a constant speed
