NASA performed an experiment to study the effects of gravitational force on humans. In order to experience twice Earth's gravity,
participants were placed in a centrifuge
54 feet long, end to end and spun at a rate of about 12 revolutions per minute.
a. What was the angular speed each person experienced in radians per second

Period is the time it takes for one “cycle” to complete. in the parent sine function, period is 2*pi since sin(0) = 0, sin(pi/2) = 1, sin(pi) = 0, sin(3pi/2) = -1, and sin(2pi) = 0. at that point, the sequence repeats itself. i’m not sure if your graph is similar to the sine function since you didn’t provide a picture, but you can find the period by looking at a graph.
