Problem

A constant horizontal force of

5\,\text{N}

is applied simultaneously to three smooth blocks A, B and C of masses

1\,\text{kg}

2\,\text{kg}

and

4\,\text{kg}

respectively. Each block is initially at rest on a frictionless surface. After

4\,\text{s}

, rank the blocks in order of (i) acceleration, (ii) speed and (iii) momentum. Give a brief justification for each ranking.
