    1. The problem statement, all variables and given/known data
    A sled slides from a slope with inclination α. A man standing on the sled ‘weighs’ an object with mass m using a spring balance. What weight does the balance indicate?

    I seem to be making it too complex, could anyone help me out with it?

    2. Relevant equations

    3. The attempt at a solution

    The object has an acceleration which is the same as the sled's (and the same direction). I suspect we are not counting air resistance.

    Yes thats correct I'm not counting air resistance!
