AN INSECT TRAVELS IN A CIRCULAR MOTION AND IT TRAVELS 6 ROTATIONS AT A TIME 31.4 SECOND FIND THE ANGULAR VELOCITY OF THE INSECT AND OBTAIN THE EXPRESSION FOR CENTRIPETAL ACCELARATION IN TERMS OF ANGULAR SPEED?

asked by FATHIMA
  1. one rotation or 2 pi radians in 31.4/6 = 5.23 seconds

    so w = angular velocity = 2 pi/5.23 = 1.2 radians/second

    A = v^2/r but v = w r
    A = w^2 r^2/r = w^2 r
