Two forces F1 = -7.50i + 6.00j and F2 = 8.40i + 7.50j are acting on a mass of m = 6.20 kg. The forces are measured in newtons. What is the magnitude of the object's acceleration?

Can you show me step by step? I'm trying to study for an exam.

    Just add the forces to get the resultant force

    f = 0.9i + 13.5j

    Since F = ma,
    a = f/m = 0.9/6.2 i + 13.5/6.2 j
    = 0.145 i + 2.177 j

    |a| = 2.18
