A point on a wheel has a constant angular velocity of 3 rad/s. The angle turned through in 15 seconds is _.
Correct answer: A. 45 rad
- A. 45 rad
- B. 10π rad5 rad
- C. 9π rad
- D. 5 rad
Explanation
According to Formula, Angular velocity = t For Angle = t = 3 15 = 45 rad So as all the options are in radian we will not convert it into degree.

About Angular Displacement
Angular displacement measures the change in a body’s angular position and is expressed in radians or degrees, with anticlockwise and clockwise directions assigned signs. It connects to arc length, angular velocity and angular acceleration, and must be distinguished from ordinary linear displacement in rotational motion.
