please please show **all work step by step** and do **each part of the question.**

You apply a constant force F (in units of N) = -50.0 i + 20.0j to a 20.0 kg box as the box travels in a straight line (along the floor) for 6.00 m in a direction that is 30 degrees CCW of +x.

a) Graph the force and displacement vectors (use a straight edge) and explain how you can tell from the graph whether the work done is positive, negative or zero.

b) How much work does the applied force F do on the box? (J)
