A spinning disk is rotating at a rate of 5 rad/s in the positive counterclock-wise direction. If the disk is subjected to an angular acceleration in the counterclock-wise direction at a rate of 2 rad/s2, Find the wheel's angular velocity in rad/s after 4 s.

ωf = 13 rad/s

Explanation:

       where ω₀ = 5 rad/s, t = 4 s, α = 2 rad/s2

as a general rule, scissors have blades less than 6 in (15 cm) long and usually have handles with finger holes of the same size. shears have blades scissors used to cut hair or fabric must be much sharper.
