In the given figure below, a 3.0 -kg block is sliding down a 60 degrees- rough incline. The speed of the block is 1.68 m/s at the instant it is 5.25 m from an uncompressed spring located at the other lower end of the incline. The spring has a spring or stiffness constant of 120 N/m and the coefficient of kinetic friction between the block and the incline is 0.35. (a) At what speed (in m/s) will the block strike the spring? (b) What would

In the given figure below, a 3.0 -kg block is sliding down a 60 degrees-
rough incline. The speed of the block is 1.68 m/s at the instant it is 5.25 m
from an uncompressed spring located at the other lower end of the
incline. The spring has a spring or stiffness constant of 120 N/m and the
coefficient of kinetic friction between the block and the incline is 0.35.
(a) At what speed (in m/s) will the block strike the spring? (b) What would
be the maximum compression (in m) of the spring?
