Question:- A wheel makes 360 revolution in 12 minute. Through how many radian does it run in one second
Answer:
π radian/second
Explanation:
1st Approach:-
Given that a wheel makes 360 revolutions in 12 minute.
12 minutes = 12 × 60 seconds = 720 seconds.
We know that in 1 revolution wheel will run 2π radian.
Thus in 360 revolution wheel will run 360 × 2π radian
= 720π radian
Our statement is reformed as Wheel run720π radian in 720 seconds.
Hence rotation in one second = 720π/720
= π radian/second
2nd Approach:-
Given that a wheel makes 360 revolutions in 12 minute.
Thus number of revolution ins one minute = 360/12
= 30 revolution/minute
Our statement is reformed as Wheel makes 30 revolution in one minute
1 minute = 60 seconds
⇒ Wheel makes 30 revolution in 60 seconds.
We know that one revolution makes an angle of 2π.
Thus 3 revolution will make run to 30×2π = 60π radian
⇒ Angle made in one second = 60π/60
= π radian/second
