Question

Having problem with the fraction part. KE=1/2mv square; solve for v.?

Answer 1

Firstly multiply by 2 both the sides and then divide by m both the sides..

Answer 2

ok so here allow me to correct it :

is it : kinetic energy = \(\large{\frac{1}{2}mv^2}\)

Answer 3

Then take the square root..

Answer 4

yes

Answer 5

@mathslover he is right..

Answer 6

r u mentioning me that reggie is right?

Answer 7

Multiply by 2 both the sides first:

\[\large mv^2 = 2(K.E.)\]

Now divide by m both the sides:

\[\large v^2 = \frac{2 \times K.E.}{m}\]

Now take the square root both sides:

\[\large v = \sqrt{\frac{2 \times K.E.}{m}}\]
