Explanation
The flywheel starts from rest and reaches 1000 rpm in 6 seconds. Assuming uniform acceleration, the average speed is half of the final speed, i.e., 500 rpm. Converting 500 rpm to revolutions per second: 500 / 60 ≈ 8.33 rps. The total revolutions = average speed × time = 8.33 × 6 ≈ 50 revolutions.
