Easy -1.8 This is a direct application of Newton's second law (F=ma) with no problem-solving required. Students simply need to recall F_net = ma, substitute m=5 and a=0.6 to get F-R=3. This is more straightforward than typical A-level questions as it's multiple choice with no calculation steps shown.
2.
An object of mass 5 kg is moving in a straight line.
As a result of experiencing a forward force of \(F\) newtons and a resistant force of \(R\) newtons it accelerates at \(0.6 \mathrm {~m} \mathrm {~s} ^ { - 2 }\)
Which one of the following equations is correct?
$$F - R = 0 \quad F - R = 5 \quad F - R = 3 \quad F - R = 0.6$$
