Ramesh observes the motion of an insect
in a circle. He finds that it travels 6 revolutions
in an anticlockwise direction for a time of
31.4sec.
a) Find the angular velocity of the
insect.
b) If the insect travels
4 revolutions in the clockwise
direction for a time of 8.6sec, what
will be the angular speed averaged
over the total time?
c) Obtain the expression for centripetal
acceleration (ac) in terms of angular
speed ( ).
