Physics: The Surface Shown In The Figure Is Frictionless?

You are balancing the the potential energy
mgh= 1/2 k x^2= 2*9.8*4 sin 30 =1/2 100 x^2

Ooh, you were close. But in addition to falling through 4m*sin30º the block ALSO falls through x*sin30º. The correct equation is
mg(d+x)sin30º = ½kx²
When I plug in your values, I get
x = 0.989 m
Hope this helps!
