1. A 31 kg crate full of fruits is placed on an incline that is
17◦ below the horizontal. The crate is connected to a spring that
is anchored to a vertical wall, such that the spring is parallel to
the surface of the incline.
(a) If the crate was connected to the spring at equilibrium
length, and then allowed to stretch the spring until the crate
comes to rest, determine the spring constant. Assume that the
incline is frictionless...
