1. The problem statement, all variables and given/known data

A child slides (starting at rest) down a 4.8 m long slide in 1.8 seconds. if the slide is inclined 28 degrees with the horizontal, what is the coefficient of friction between the child's pants and the slide?

2. Relevant equations

m a = u mg => u =a/g

3. The attempt at a solution

Beats the heck out of me. I tried solving for the x and y components, but I'm really just not entirely comfortable with the question in general. I don't even know if the formula I listed is on the right path. This is my first time posting, so I'm not really sure what the rules of solving (obvious) homework problems, but I was really hoping for a run-through of the formulas (minus values), and maybe an explanation to go along with it. Thanks!
