Problem

Four statements relating to the derivation of

F = ma

are given below: P. Write

F = \dfrac{\Delta p}{\Delta t}

Q. Substitute

\Delta p = m(v - u)

R. Recognise

a = \dfrac{v - u}{t}

S. Obtain

F = ma

Which sequence of these steps (from first to last) correctly derives

F = ma

? a) P → R → Q → S b) P → Q → R → S c) Q → P → R → S d) P → Q → S → R
