The angular momentum (L) can be calculated using the formula L = I * α * t, where I is the moment of inertia, α is the angular acceleration, and t is the time. First, find α using τ = I * α, where τ is the torque. So, α = τ / I = 0.11 / 0.034. Then, L = I * α * t = 0.034 * (0.11 / 0.034) * 8 = 0.88 kg·m²/s.
