(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A 2.00kg mass starts from rest and slides down a frictionless inclined plane that makes an angle of 30 degrees with the horizontal. Determine its speed after it has slid a distance of 3.00m down the ramp.

2. Relevant equations

I am leaning about Laws of Conservation of Energy

∑E_{k}=∑E_{p}

E_{k}=(1/2)mv^{2}

E_{p}=mgh

maybe SOH CAH TOA to get the height

3. The attempt at a solution

using a height of 2.5980, from 3cos(30), i put that into my equation but got 7.1396 m/s

when i know the answer is 5.4 m/s???¿¿
