What is the value of linear velocity, if \(\vec{\omega} = 3\hat{i} - 4\hat{j} + \hat{k}\) and \vec{r} = 5\hat{i} - 6\hat{j} + 6\hat{k}
Text Solution
Verified by ExpertsThe correct answer is:
D
\(\vec{v} = \vec{\omega} \times \vec{r} = \begin{vmatrix} \hat{i} & \hat{j} & \hat{k} \\ 3 & -4 & 1 \\ 5 & -6 & 6 \end{vmatrix} = -18\hat{i} - 9\hat{j} + 2\hat{k}\)
