Question

A particle executes simple harmonic motion along a horizontal line. The graph of the particle's position as a function of time is shown in the diagram below. Note that the x displacement of the particle is plotted on the vertical axis and time is plotted on the horizontal axis. Each unit on the vertical axis is 2 m and each unit on the horizontal axis is 2 s. (Use the exact values you enter to make later calculations.)What is the amplitude of motion for this particle?What is the period of oscillation for this motion?What is the frequency for this motion?

Explanation / Answer

amplitude = 5 units period of oscillation = 4s frequency = 1/4 = 0.25 Hz
