# F=ma calculation in vector format

I am given F=(3i + 2j + 4k) N and mass = 2kg

I need to calculate acceleration, so I plugged it into F=ma,
am I right in saying

(3i + 2j + 4k) = 2 a

$$\frac{(3i + 2j + 4k)}{2}$$ = a

therefore a = 1.5i + 1j + 2k ?

cheers.

Looks good to me. I assume i, j and k are unit vectors in 3 perpendicular directions.
