 Homework Statement

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
1.m
2.m to the power 0
3.m to the power 0.5
4.m to the power 0.5
 Relevant Equations

1/2m(v² u²)=F*d
F=m*a
v²u²=2a*d
Initial velocity u=0
Let Final velocity be v
Then, KE acquired by the object=1/2mv²
So the answer must be option1 i.e. m¹
But my textbook says the answer is m to the power zero.Please explain this discrepancy.
