Centripetal force

  1. Jan 9, 2008 #1
    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 Speed= C/T Speed (radians/sec)
    5 30 s 6 s 1.05 m/s 120pi
    10 23.62 s 2.36 s 2.66 m/s 94.5pi
    15 19.78 s 1.32 s 4.76 m/s 79pi
    20 16.85 s .84 s 7.48 m/s 66.3pi
    25 15.72 s .63 s 9.98 m/s 63pi
