A 2.0 kg package is released on a 53.1◦(adsbygoogle = window.adsbygoogle || []).push({});

incline, 4.0 m from a long spring with force

constant 120 N/m that is attached at the

bottom of the incline. The coefficient of

friction between the package and the incline

are µs=0.40 and µk=0.20. The mass of the

spring is negligible.

a. Show that the maximum

compression of the spring is 1.06m.

b. The package rebounds back up the

incline. Show that the package

comes to rest at a distance 1.32 m

below its initial position.

I'm not even quite sure where to begin on part a, and I don't even understand what they are asking for on part b. For part a, it seems like it might be a conservation of energy problem, but I'm not sure how to set up the equation. Any hints would be greatly appreciated!!
