Homework Help: F=ma calculation in vector format

  1. Jan 10, 2009 #1
    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 ?

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