Question

kinetic energy of a body is K then the expression used to find it's velocity is ​

Answer 1

Answer:

K=1/2mv^2

Explanation:

2k=mv^2

2k/m=v^2

Sqrt of 2k/m=v

Answer 2

Answer:

The value of kinetic energy in terms of velocity would be sqrt 2\frac{K}{m} =v

Explanation:

We have always known that when mass is multiplied with square velocity.

We get the kinetic energy and we are given that for a certain mass the kinetic energy for that mass is given as K.

So let us jot down the values and find out what would be the value of k.

K = $\frac{1}{2} mv^2$

So, now rearranging these values we get  

$2K= mv^2$

Or again we can write it as $\sqrt {2\frac{K}{m}} = v$.
