A wheel rotates about a fixed axis with an initial angular velocity of 20 rad/s. During a 5.0-s interval, the angular velocity increases to 40 rad/s. Assume that the angular acceleration was constant during the 5.0-s interval. How many revolutions does the wheel turn through during the 5.0-s interval?

Explanation:

Given that,

Initial angular velocity,

Final angular velocity,

Time, t = 5 s

We need to find the total number of revolution made by the wheel during the 5 seconds interval. The first equation of motion gives the acceleration of the wheel as :

To find the number of revolution, use third equation of motion as :

1 revolution = 6.28 radian

So, the wheel will make 19 revolution during the 5 seconds interval.
