The correct answer is:
$400 \mathrm{kgm}^{2} / \mathrm{s}$
$\tau=50 \mathrm{Nm}$ for 8 second initially at rest
$\vec{L}=\vec{\tau} \cdot t \quad$ for constant $\vec{L}$ $\vec{\tau}$
$|\vec{L}|=400 \mathrm{~kg} \mathrm{M}^{2} / \mathrm{S}.$
$\vec{L}=\vec{\tau} \cdot t \quad$ for constant $\vec{L}$ $\vec{\tau}$
$|\vec{L}|=400 \mathrm{~kg} \mathrm{M}^{2} / \mathrm{S}.$
