Question 3:
A wheel makes 360 revolutions in one minute. Through how many radians does it turn in one second?
Answer
Number of revolutions made by the wheel in 1 minute = 360
∴Number of revolutions made by the wheel in 1 second = 360/60 = 6
In one complete revolution, the wheel turns an angle of 2π radian.
Hence, in 6 complete revolutions, it will turn an angle of 6 × 2π radian,
i.e., 12 π radian
Thus, in one second, the wheel turns an angle of 12π radian.
