Explanation:
let velocity =v,mass=m
therefore inital Kinetic energy(KE)=1/2mv^2
now mass is made 2m and velocity is made 3v
final Kinetic energy (KE')=1/2(2m)(3v)^2
=(1/2mv^2)×18
=KE ×18
therefore KE is increased 18 times

Taking
and marking it as equation 1
we take ATQ
we get
=
therefore kinetic energy becomes 9 times
