12 Two constant forces act on a particle, of mass 2 kilograms, so that it moves forward in a straight line. The two forces are:

a forward driving force of 10 newtons
a resistance force of 4 newtons.

Find the acceleration of the particle.
Circle your answer.
\(2 \mathrm {~m} \mathrm {~s} ^ { - 2 }\)
\(3 \mathrm {~m} \mathrm {~s} ^ { - 2 }\)
\(5 \mathrm {~m} \mathrm {~s} ^ { - 2 }\)
\(12 \mathrm {~m} \mathrm {~s} ^ { - 2 }\)
