Question

an object of mass 10kg with velocity of 6m/s then the k.E will be?

Answer 1

Answer:

If the mass of the body is doubled and its velocity is halved, find the ratio of the initial kinetic energy to the final kinetic energy.

Explanation:

I hope this answer is help you so please say thanks

Answer 2

Explanation:

$\huge\underline\purple{Answer}$

Given:-

an object having

mass(m)=10 kg

velocity(v)=6 m/s

To find:-

K.E (kinetic energy)

Solution:-

As we know

$\large\blue{\boxed{\green{K.E=}{\binom{1}{2}} \times{mv}^{2}}}$

$\implies{K.E=}{\binom{1}{2}} \times{10} \times{6}^{2}$

$\implies{K.E=}{\binom{1 }{2}} \times{10} \times{36}$

$\implies{K.E=}{\binom{1}{2}} \times{360}$

$\implies{K.E=}{\binom{360}{2}$

$\implies{K.E=}<strike>{\binom{360}{2}}</strike>$

$\implies{K.E=180kj}$

Hence your answer
