Kamron Osborn · Answer 1

v = Square Root of StartFraction 2 times K E over m EndFraction.

Explanation:

Kinetic Energy, K. E = 1/2 * mass * velocity squared

K. E = 1/2 * mv2

Hence v2 = (2 * K. E) / m

v = √ 2K. E/m

Expressing it in computer language we have:

v = Square Root of StartFraction 2 times K E over m EndFraction.
