Work-Energy Theorem

The kinetic energy acquired by a mass $m$ in travelling distance $d$ , starting from rest, under the action of a constant force is directly proportional to

Show answer and solution

Answer: (b)

Work-energy theorem: $K = W = Fd$ (starting from rest).
$F$ and $d$ are fixed, so $K$ does not depend on $m$ : $K \propto m^0$ .
So the answer is (b).
