This isn't really a homework question... but it is homework... and I have a question... so I thought I might as well post it here.(adsbygoogle = window.adsbygoogle || []).push({});

This is part of my grade 12 Physics curriculum. For our project, we're supposed to ask ourselves "What if <this happened>?"

I chose to do mine on negative mass.

I have attached my progress so far (.doc format), and I wanted to hear if someone knowledgable could verify some of my theories...

I think everything is right... but I'm not so sure about my conclusion about friction.

If [TEX]F_{f} = \mu mg[/TEX] (F_{f} = \mu mg) and m is negative, then friction might actually be in the opposite direction, cancelling out the negative acceleration. But I'm still not so sure. Give er' a read if you'd like to help me out, and let me know.

Thanks.

Edit:I also realized my Free Body Diagram is incorrect for the freefall question. Gravity should be up because Fg = mg. But acceleration is still down because accel is opposite of Fnet.
