A atom can become an ion with a -2 charge, if it gains 2 electrons during a chemical reaction.
Given:
w = z(t)= γ − β*t^2
Differentiating both sides with respect to t, we get:
α = z(t) = -2βt
Given: <span> γ = 5.35 rad/s and β = 0.810 rad/s3
</span>
so, For t = 3 sec,
angular acceleration = -2 * 0.810 * 3 = <span>-4.86</span>
