**1,**

In this problem, we use the equation:

$\overline{){\mathbf{F}}{\mathbf{=}}{\mathbf{k}}{\mathbf{x}}}$, where F is force, k is spring constant, and x is the change in spring length.

Solving for k:

1. If a force of 20 N stretches a spring 0.5 m, what is the spring constant?

a. 10 N/m

b. 20 N/m

c. 60 N/m

d. 40 N/m

2. A wave has an amplitude of 58 cm. It has a period of 0.43 seconds. What is the angular velocity (w)?

a. 2.70 rad/s

b. 3.97 rad/s

c. 14.612 rad/s

d. 58.0 rad/s
