If mass will be constant and velocity be tripled then the very change will happen in kinetic energy. which is following,
since we know that,,,
K.E = 1/2*m (v)^2
so ,,now required K.E = 1/2 * m *(3*v)^2
=1/2*m*9v^2
then change in K.E = Required K.E/K.E
=1/2 * 9mv^2 by 1/2* mv^2
= 9
means K.E will be increases 9 times from beginning.
