The K.E. of a body can be increased maximum by doubling its:
mass
weight
speed
density

$K . E = \frac{1}{2} m v^{2}$

$K . E \propto m$ & $K . E \propto v^{2}$
So doubling mass will double the kinetic energy and doubling speed will make kinetic energy $4$ times.

$∴$ The K.E. of a body can be increased maximum by doubling its speed.

The K.E. of a body can be increased maximum by doubling its:massweightspeeddensity

K.E=12mv2K.E∝m & K.E∝v2So doubling mass will double the kinetic energy and doubling speed will make kinetic energy 4 times.∴ The K.E. of a body can be increased maximum by doubling its speed.
