ooh i understand it now! Thanks eeryone

well since the a vs t graph is a cosine function, wouldn't the x vs. t graph be a negative cosine function? (basically the same thing--inverted?)

Homework Statement Using the acceleration as a function of time graph, we are required to sketch the position as function of time graph Homework Equations I know that the position vs. time graph is a cosine wave and the aforementioned is a sine wave. I have NO idea how to start...

we did a lab in physics recently in which we whirled a rubber stopper at a given radius (1 meter) for 30 rev and timed it. below, are the values we got. i' not sure if i am converting the linear peed to radians/sec correctly. any input? Centripetal Force Period for 30 revolutions Period=T...
