As we know that K.E = 1/2 mv² so
 by arranging it 
K.E ×2÷6 = v²
now by putting values
v²=13.33 m²/s²
so
v= 3.65 m/s....

The formula to find kinetic energy is -

[latex]K.E. = \frac{1}{2}*m* v^{2} [/latex]

Where,

[latex]m = mass[/latex]

and

[latex]v = velocity[/latex]

So, putting the values in the formula we get -

[latex]40 = \frac{1}{2} *6*v^{2} [/latex]

[latex] \frac{40}{3} = v^{2} [/latex]

[latex] \sqrt \frac{40}{3} = 3.6514 m/s[/latex]
