Example 2

-1
A car moving at a velocity of 36 ms . Calculate the angular velocity of rotation of the car wheel
if the radius of the wheel is 80 cm

Solution:

Angular velocity,  =

3.6
 =
0.8

 = −1

Example 3

-1
A man speeding bike so that the angular velocity of the bicycle wheels increases of 3 rad s to 6
-1
rad s in 8 seconds. If the radius of bicycle wheel that is 0.6 m, what is the angular acceleration
and linear acceleration of the wheel.

Solution:

 = 3 −1 , = 6 −1 , = 8 , = 0.6
2
1

 =  + 
2
1

 − 
 = 2 1

6 − 3
 =
