A block of mass m slides freely in the x -direction with velocity \( \mathbf{v} = v\hat{i}\) , as shown in the figure. The angular momentum of the block about origin A and origin B is calculated as follows. What is the angular momentum \( L_B\) about origin B ?
1
\(L_B = 0\)
2
\(L_B = mvl\hat{k}\)
3
\(L_B = mvl\hat{j}\)
4
\(L_B = mv\hat{i} \)
