A wheel has an angular acceleration of 4 rad/s². If it starts fro...
The number of revolutions (N) completed by a wheel can be calculated using the formula:
N = (ω₀t + (1/2)αt²) / (2π)
N = (ω₀t + (1/2)αt²) / (2π)
where:
ω₀ = initial angular velocity (0 rad/s, as the wheel starts from rest),
t = time, and
α = angular acceleration.
ω₀ = initial angular velocity (0 rad/s, as the wheel starts from rest),
t = time, and
α = angular acceleration.
Simplifying the formula for the given scenario:
N = (1/2)αt² / (2π)
N = (1/2)αt² / (2π)
Substituting the given values:
N = (1/2) * 4 rad/s² * (10 s)² / (2π)
N = 80 revolutions
N = (1/2) * 4 rad/s² * (10 s)² / (2π)
N = 80 revolutions
Therefore, the wheel will complete 80 revolutions in 10 seconds.
