Question

Which formula can be used to find velocity if kinetic energy and mass are known? v = The square root of one half times K E and mass. v = Square Root of StartFraction 2 times m over K E EndFraction. v = Square Root of K E times m v = Square Root of StartFraction 2 times K E over m EndFraction.

Answer 1

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

Step-by-step 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.

Answer 2

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