Ore Cars

How do i do this physics question?

An ore car of mass 35000 kg starts from rest
and rolls downhill on tracks from a mine. At
the end of the tracks, 17 m lower vertically, is
a horizontally situated spring with constant
4.6 × 105 N/m.
The acceleration of gravity is 9.8 m/s2 .
Ignore friction.
How much is the spring compressed in stop-
ping the ore car?
Answer in units of m.

Anyone who can help me i would greatly appreciate it and i will give as many points as i can to those who do help me promise.

Let:
m be the mass of the truck,
h be the vertical descent,
k be the spring constant,
x be the spring compression,
g be the acceleration due to gravity.

Equating the final energy stored in the spring to the truck's initial potential energy:
kx^2 / 2 = mgh
x^2 = 2mgh / k.

x = sqrt[ 2 * 35000 * 9.81 * 17 / (4.6 * 10^5) ]
= 5.04m to 3 sig. fig.
