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 [tex]\frac{(3i + 2j + 4k)}{2}[/tex] = 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.
