Problem

If the displacement

s

of a body is measured in metres (m) and the time

t

is measured in seconds (s), what is the physical unit of

\dfrac{ds}{dt}

? a)

\text{second per metre (s/m)}

\text{metre per second (m/s)}

\text{metre per second squared (m/s}^2\text{)}

d) dimensionless (no unit)
