An insect trapped in a circular ambush of radius 10 cm moves along the ambush and completes 12 revolutions in 20s.
What is the angular speed and the linear speed of the motion ?

Explanation

We are given
`R = 10 cm and n = (12)/( 20) s ^(-1) = 0. 6 s ^(-1).`
We are to calculate,
Angular speed `omega,` linear speed v and magnetide of acceleration. and ` a = omega ^(2) R implies a = 4 pi ^(2) n ^(2) R ^(2).`
Linear speed , `v = 2 pi n R = 2 xx (22)/(7) xx 0. 6 xx 10 = 37.7 cm s ^(-1).`
