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]
