Homework Statement

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?

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 that's correct I'm not counting air resistance!
