A block with mass m = 2.00 kg is placed against a spring on a frictionless incline with angle = 30.0Â° (Figure 8-43). (The block is not attached to the spring.) The spring, with spring constant k = 19.9 N/cm, is compressed 24.0 cm and then released.

How Far along the incline is the highest point from the release point?

I've managed to get the elastic potential energy of the spring (57.312 J) and the accompanying change in gravitational potential energy to the highest release point (also 57.312 J). Thanks!
