An insect trapped ina circular groove of radius 12cm moves along he groove steadily and completes 7 revolutions in 100s.
(a) What is the angular speed, and the linear speed of the motion?
(b) Is the acceleration vector a contant vector? What is its magnitude?

Explanation

This is an example of uniform circular motion.
Here R = 12 cm .
The angular speed `omega` is given by
`omega = 2pi//T = 2pixx7//100=0.44rad//s`
