thank you so much! you have no idea how much that helped me

okay so if Ff = μ*Fn then... μ*mg*cos30 + mg*sin30

OHHH! μ*mg*sin30 + mg*cos30

mg*cos30 + mg*sin30 ??!??

mg * cos30

mg * sin30

I'm thinking it's probably tangent, but I have no idea why

for 1 degree, it's effected by cos(1), then for 2 degrees it's cos(2) etc.

Would it be -9.8?

Oh, none because Gravity is in the y-axis and the skiers motion is in the x... So, does that mean at 90° gravity would cause him to decelerate?

If i's 0, the Gravitational force is equal to mass*9.8. If it's 90, I'm not exactly sure

It increases it...?

friction is opposite of the skiers motion, parallel to the surface & gravity is straight down
