## Homework Statement

## Homework Equations

W= KE

Wspring = .5kx^2

## The Attempt at a Solution

since W = .5mv^2 = Wspring = .5x^2

i solve for v and get that v = sqrt(kx^2/m)

if i plug in multiply the x by 2, the 2 squares and i get 4. the square root of 4 is just 2 and it comes out as a constant , and so velocity is 2 times faster

Did i go through the problem correctly?[/B]
