Question

Which formula can be used to find velocity if kinetic energy and mass are known?

V=
-(KE)(m)
V=
2 m
KE
V=
KE(m)
2 KE
V=
m

Answer 1

it's D on edge2021

Step-by-step explanation:

Answer 2

`v = \sqrt{ (2ke)/(m) }`

option D is the correct option.

Here,

If an object of mass 'm' moving with a velocity'v' then,

`kinetic \: energy = (1)/(2) m {v}^(2) \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: {v}^(2) = (2ke)/(m) \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: {v}^(2) = \sqrt{ (2ke)/(m) }`

hope this helps...

Good luck on your assignment..
