## Homework Statement

A child goes down a playground slide with an acceleration of 1.26 m/s^2. Find the coefficient of the kinetic friction between the child and the slide if the slide is inclined at an angle of 33 degrees below horizontal.

## Homework Equations

F=MA

Kinetic Friction = (Coefficient)N

## The Attempt at a Solution

I'm assuming I need to find the X and Y components using 33 degrees and gravity?

(-9.81Cosine(-33) = -8.66

(-9.81)Sin(-33) = 4.6

Now I'm pretty lost. I'm having a hard time understanding how f=ma and F

_{k}= (μ

_{k})N relate to each other.

I think I can plug in MA into N? Fk = (uk)(ma) ?
