How do you go about solving this problem?

How long does it take a slide loving pig to slide 2 m down a 30° incline (the incline is measured from the
horizontal) with a coefficient of static friction of 0.35 and a coefficient of kinetic friction of 0.30?

a=g sin30 - k g cos30
where k=coefficient of kinetic friction
x=1/2 a t^2 + V0 t
v0= initial velocity ; in your problem V0=0
so you can calculate t
