In the given figure below, a 3.0-kg block is sliding down a 60°.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? 5.25 m A 60° ww
