Question

Transcribed Image Text:Two position vectors are given by
\(\vec{A} = (4.00 \, \text{m})\hat{i} - (2.00 \, \text{m})\hat{j} - (3.00 \, \text{m})\hat{k}\)
and
\(\vec{B} = (4.00 \, \text{m})\hat{i} - (5.00 \, \text{m})\hat{k}\).
What is the scalar product of \( (3\vec{A}) \cdot \vec{B} \)?
Options:
- \((16.0 \, \text{m}^2)\hat{i} + (15.0 \, \text{m}^2)\hat{k}\)
- \(31 \, \text{m}^2\)
- \((48.0 \, \text{m}^2)\hat{i} + (45.0 \, \text{m}^2)\hat{k}\)
- \(93 \, \text{m}^2\)
- None of the above.
