Simple Harmonic Motion

Suppose we have a mass of 100 g hanging from a spring with a spring constant of k, as in Figure 1. The spring makes one complete oscillation in 0.125 sec, covering 30 cm from top to bottom.

1. Find the following properties of the system. a. What is the period of the system? Explain.

b. What is the frequency of the system? Explain.

c. What is the angular frequency of the system? Explain.

d. What is the amplitude of the system? Explain.

Figure 1: A 100 g mass hanging vertically on a spring, as shown in the PhET simulation.

2. Draw the vertical motion of the system over time and come up with an equation to describe this motion. On this plot, indicate where the velocity and acceleration are at a maximum.

3. How would the motion of the spring change if the mass were doubled to 200 g?
