## Homework Statement

[/B]

The block, initially at rest, slides down the ramp and compresses the spring 0.03 m.

Theta = 30 degrees

L = 1.25 m

M of block = 2 kg

Δx = 0.03 m

1) Write the expression for the initial and final energy states

2) Find the spring constant K

## Homework Equations

mgh = 0.5kx

^{2}

## The Attempt at a Solution

Can I say that when the block compresses the spring and comes to rest, h=0, in which case I wouldn't have to include mgh on the right hand side of the energy equation?

mg(L*sin theta) = 0.5*k*(x

^{2}) and solve for k...

This seems too easy, am I approaching this wrong?
