A 2.0 kg package is released on a 53.1◦
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!
