Hi friend
----------------
Your answer
---------------------

Given velocity = v

Suddenly the velocity is tripled.

So, new velocity = 3v

Then,
------------

Kinetic energy= 1/2 × m × v²

New kinetic energy = 1/2 × m × (3v)²

Their ratio=
 \frac{ \frac{1}{2}  \times  \: m \times (3 v) {}^{2} }{ \frac{1}{2}  \times  \: m \:  \times v {?}^{2} }  \\  \\  =  >  \:  \frac{9v {}^{2} }{v {}^{2} }  \\  \\  =  >  \:  \frac{9}{1}  \\  \\  =  > ratio \:  = 9 \: is \: to \: 1
Therefore,
-----------------

The ratio is = 9:1

HOPE IT HELPS
