Given:
Slope, θ= 30 degrees
Coefficient of kinetic friction, μ = 0.10
Let's find the following.
(a) Acceleration of the skier.
To find the acceleration of the skier, apply the formula:

Since we are to find acceleration, rewrite the equation for a:

Where:
g is the acceleration due to gravity = 9.8 m/s²
μ = 0.10
θ= 30 degrees
Thus, we have:

Therefore, the acceleration of the skier is 4.05 m/s².
