Newtons 2nd Law please help

  1. Nov 13, 2012 #1
    A 2.5 kg mass accelerates at 6.1 m/s
    in adirection 37◦north of east. One of the two
    forces acting on the mass has a magnitude of
    6.05 N and is directed north.
    Determine the magnitude of the second
    force.
    Answer in units of N



    I know you have to break it up into multiple components, but otherwise i don't have a clue of what to do

    If a mass accelerates in a certain direction, the net force applied to the mass must act in the same direction.

    F = ma is a vector equation.

    ya, key word here is net force, two forces accelerating at 6.1m/s/s, one of which was given, just get the N and magnitude correct for the other.

    if you are the marker for my exam, i think i'll be gone! amended the units for acceleration.....hahaha

    Just pointing out the acceleration is 6.1 m/s2. It was beginning to bug me now that I've seen it in multiple threads :-)
