    Hello jpc, welcome to PF :smile: !

    If your post wasn't moved here from another forum, you must have seen the homework template flash by. And deleted it by accident. It is very useful however, and even mandatory in these PF forums. So indulge us and complete your post, please.

    The problem statement looks OK. Now the remainder:

    1. The problem statement, all variables and given/known data

    2. Relevant equations

    3. The attempt at a solution
