## Homework Statement

A 20kg object is on a 10 m long, 15 degree slope , that has a coefficient of friction that is 0.2 Calculate the time to slide down the final velocity at the bottom

**2. Homework Equations [/b**

Fg=mag

Fn=Fgcos(theta)

Fp=Fgsin(theta)

mu=Ff/Fn

Fr=MAr

I have gotten to the Fr=MAr stage, but after that where you substitute for Vf, Vi, S, Ar, and T; I have gotten stuck.

Any hints or tips would be greatly appreciated, thanks for your time
