A crate of mass 0.812 kg is placed on a rough incline of angle
35.3 degrees. Near the base of the incline is a spring of spring
constant 1140 N/m. The mass is pressed against the spring a
distance x and released. It moves up the slope
0.154 meters from the compressed position before
coming to a stop. If the cofficient of kinetic friction is 0.195,
how far (m) was the spring compressed?
