My teacher made this question:
Iceman is sliding down a 10.0 x 10^(-8) nm ice that is inclined at 20.0 degrees with respect to the horizontal. Iceman is initially at rest. The coefficient of kinetic friction between iceman's feet and the ice is 0.100. Determine Iceman's speed at the bottom of the ice slide.
What I know:
1)There are 3 forces as he slides down this slide: force gravity going straight down, force normal which is parallel to the slide @ 20.0 degrees, and force friction which is in the opposite direction he slides down.
2)The slide is 1m.
3)ΣFnet= m ⋅ anet ... I then attempted to split it into x and y accordingly where ΣFnetx = m ⋅ anetx &
ΣFnety = m ⋅ anety
4) Force friction is equal to -(μ)Fn
5)Fnety= Fgy + Fn
