Question

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 ( ).

Answer 1

Answer:

Explanation: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 ( ).
