Problem

A 2.0 kg2.0\,\text{kg} block is attached to a horizontal spring with constant 150 N/m150\,\text{N/m} on a table where the coefficient of static friction is 0.200.20. Starting from the spring’s relaxed length, the block is slowly pulled outward until it is on the verge of sliding. How far has the spring been stretched at that instant? (Use g=9.8 m/s2g = 9.8\,\text{m/s}^2.) (a) 5.2 cm5.2\,\text{cm} (b) 1.3 cm1.3\,\text{cm} (c) 2.6 cm2.6\,\text{cm} (d) 13 cm13\,\text{cm}
