The formula for the velocity, v is √2E/m
Kinetic energy is half the mass multiplied by the square of the speed of the object
It is written thus;
Kinetic energy = 1/ 2 × m × v²
To solve for 'v' mean that we should make 'v' the subject of formula
E = 1/ 2 mv²
E = [tex]\frac{mv^2}{2}[/tex]
cross multiply
[tex]2E = mv^2[/tex]
To make 'v' the subject, we have
[tex]v = \sqrt{\frac{2E}{m} }[/tex]
Thus, the formula for the velocity, v is √2E/m
