Hey everyone, i'm new here, and just wanted to say hi first. Second, I was wondering if anyone would so kind as to help me with this problem.

An 80kg skiier has a force of 200N exerted on him down the slope. Now i've already found the acceleration of 2.5m/s^2, however, now i need to work out whether the slop is more than 45 degrees. I understand I need to use the gsincos equation, but i'm getting nowhere in using it. If anyone could explain how I'm able to find whether the slope is greater than 45 degrees or not, then i'd really appreciate it. Thanks

Not sure if im on the right track but.

Sincos = a/g = 2.5/9.8
