Question

which of the following are possible units for acceleration?

~ the dashed line represents an underline.

A. cm/s
-----------
s


B. m * s
-----------
s


C. km/h/s


D. min
-----------
min/km


Would A-C all be possible units for acceleration? I don't think D would be correct because it is time over time and that doesn't seem possible.

Answer 1

A and C are possible units, but m/s^2 is the preferred unit.

C should be written
(km/h)/s or km/(h*s)
