Would anyone help me with this question, please?

We don't do homework, Amelia, but will help if you have a specific and narrow question. What have you done so far?

That's not a home lesson, I'm training to get VBA applied in calculations of Physics, and most of the materials that I found has proposed exercises without feedback ..
I tried to make a macro but dont know if that's correct, I saw in a video tutorial someone doing this way
