Problem

Two perpendicular forces,

F_{1}=6\,\text{N}

due east and

F_{2}=8\,\text{N}

due north, act simultaneously on a particle of unknown mass. The resulting acceleration of the particle is

5\,\text{m\,s}^{-2}

towards the north-east. Determine the inertial mass of the particle. (a)

2.8\,\text{kg}

(b)

1.0\,\text{kg}

(c)

2.0\,\text{kg}

(d)

1.6\,\text{kg}
