Homework Help: Potential energy curves

  1. Apr 8, 2010 #1
    1. The problem statement, all variables and given/known data

    A particle of mass m = 3.0 kg moves along the x axis through a region in which its potential energy U(x) varies as shown in the Figure. When the particle is at x = 8.5 m, its velocity is 2.273 m/s.

    D.) What is its speed at x = 14.0 m ?

    2. Relevant equations

    ET= mgh+.5mv^2

    3. The attempt at a solution

    I keep getting it wrong, can someone gear me to the right direction?
