Hi please help with C and D and how to solve them! thanks!

For each situation below, a person pushs a 20-kg crate along a horizontal surface with friction. However, in each case the person pushes in a different direction. Complete the following activities for each situation. Assume that g = 10 m/s2. (a) Determine by graphical analysis the magnitude of the normal force of the surface up on the crate. (b) Determine the magnitude of the kinetic friction force assuming a 0.20 coefficient of kinetic friction. (c) Graphically determine the net force in the x direction and the acceleration in the x direction. (d) Apply Newton's second law in component form using symbols and numbers shown in the diagrams.
