A 300 gram block is attached to a light horizontal spring. The block is free to slide on a horizontal table. A force of 25 N compresses the spring 20 centimeter.
a. Find what is the spring constant, k?
b. Find how far beyond its equilibrium position will the spring stretch at its first maximum extension if the surface of the table is frictionless?
c. Find how far beyond its equilibrium position will the spring stretch at its first maximum extension if the coefficient of kinetic friction of the table surface is 0.20?
