NEET 2026 Physics Angular Kinematics MCQ Question
The angular speed of a flywheel is increased from 600 rpm to 1200 rpm in 10 s. The number of revolutions completed by the flywheel during this time is:
900
600
150
300
Correct Answer
Detailed Explanation
Using the equation of motion for angular velocity and acceleration, the number of revolutions is calculated as θ/2π, where θ is the angular displacement. This results in 150 revolutions.
