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

A 11 kg box slides 4.0 m down the frictionless ramp shown in the figure , then collides with a spring whose spring constant is 190 N/m. The angle of the ramp is 30°. What is the maximum compression of the spring?

2. Relevant equations

Ei=mgh

Ef=1/2kx^2

3. The attempt at a solution

Ei=Ef

mgh=1/2kx^2

mgLsinθ=1/2kx^2

11(9.8)(4sin30)=1/2(190)x^2

1.5m = Max compression

I swear this is right but it's not, can anyone help me out?
