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>
Answer:
a = 10 m/s²
Explanation:
<u><em>Given:</em></u>
Force = F = 50 N
Mass = m = 5 kg
<u><em>Required:</em></u>
Acceleration = a = ?
<u><em>Formula:</em></u>
F = ma
<u><em>Solution:</em></u>
<em>Rearranging the formula for a</em>
=> a = F/m
=> a = 50/5
=> a = 10 m/s²
