Work Incline Problem: Find Distance Up Incline for Block w/ No/Low Friction

[xjasonx1]

Homework Statement

A 230 g block is pressed against a spring of force constant 1.20 kN/m until the block compresses the spring 10.0 cm. The spring rests at the bottom of a ramp inclined at 60.0° to the horizontal. Use energy considerations, determine how far up the incline the block moves before it stops under the following conditions.
(a) if there is no friction between block and ramp
(b) if the coefficient of kinetic friction is 0.400

I am not sure if my assumption is correct. The block starts is released at rest so the in\Deltaitial velocity is zero and the question is asking for the distance at rest so the final velocity is zero making
$$\Delta$$K zero.

Hi xjasonx1!

(have a delta: ∆ )

Yes, ∆KE is zero.
