Example 4.10 An insect trapped in a
circular groove of radius 12 cm moves along
the groove steadily and completes 7
revolutions in 100 s. (a) What is the
angular speed, and the linear speed of the
motion? (b) Is the acceleration vector a
constant vector? What is its magnitude ?
Answer This is an example of uniform circular
motion. Here R= 12 cm. The angular speed ois
given by​

Answer 1

Answer:

A) angular speed is 0.14 pie

B) acceleration is zero

since acceleration is radius × angular speeds square

that is zero
