What is the SI unit and nature of velocity according to the summary table?
Ametre (m), scalar
Bmetre/second (m/s), scalar
Cmetre/second$^2$ (m/s$^2$), vector
Dmetre/second (m/s), vector
Answer & Solution
Correct answer: D. metre/second (m/s), vector
The summary table lists velocity as having SI unit metre per second, $\text{m/s}$, and being a vector quantity. Option B is the unit of velocity but gives the wrong nature.
