    Hi David Millson. Welcome to PF.

    Your question is one that's appropriate for one of the homework help forums. Select one here: https://www.physicsforums.com

    However, when you post there you'll need to show your attempt at solving the problem, otherwise your question will be deleted because you have shown no effort. That's how our homework help forums work.

    Good luck with your studies.

    I'm 74 and have had Multiple Sclerosis for 28 years. It was a question I need to answer in my defense against a Vermont State Trooper's perjury. Will you help me?
