Question

A centrifuge’s angular velocity is initially at 159.0 radians/second to test the stability
of a high speed drill component. It then increases its angular velocity to 999.0
radians/second. If this is achieved in 4,100.0 radians what is the angular acceleration
of the centrifuge?

    Answer:

    118.6 rad/s²

    Explanation:

    Δθ = 4100.0 rad

    ω₀ = 159.0 rad/s

    ω = 999.0 rad/s

    Find: α

    ω² = ω₀² + 2αΔθ

    (999.0 rad/s)² = (159.0 rad/s)² + 2α (4100.0 rad)

    α = 118.6 rad/s²
