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?

Question
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?

![Khufra works at a spring factory and he was assigned to test a certain
spring, whose constant is 50 N/m, attached to a 50-kg block in an incline
(0=30°). With the spring initially at equilibrium position, the block was
pulled 0.3 meters down the incline by a 50-N external force applied
parallel to the path. If the coefficient of kinetic friction is 0.3, determine
the: a) normal force (in Newtons) b) work done by the spring (in Joules)
