Question

A rocket is moving up with a velocity 'v' ,if the velocity of the rocket is suddenly triplet ?Sayreville be the ratio of the two kinetic energy

Answer 1

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
