Chapter 13, Vibrations and Waves182 CHAPTER 1313.1 Hooke’s Law 1. The SI base units for spring constant are which of the following? a. kg·s2b. kg/m2c. kg/s2d. kg·m22. A large spring requires a force of 150 N to compress it only 0.010 m. What is the spring constant of the spring? 3. A 0.20-kg object is attached to a spring with spring constant k= 10 N/m and moves with simple harmonic motion over a horizontal frictionless surface. At the instant that it is displaced from equilibrium by -0.050 m, what is its acceleration? 4. Tripling the weight suspended vertically from a coil spring will result in a change in the displacement of the spring’s lower end by what factor? 5. Tripling the displacement from equilibrium of an object in simple harmonic motion will bring about a change in the magnitude of the object's acceleration by what factor? a. 0.33 b. 1.0 c. 3.0 d. 9.0
