What is the ratio of the kinetic energy of an object of mass 3m moving at speed 2v to an object of mass m/2 moving at a speed v?
The ratio of kinetic engery between two objects having mass as 3m and m/2 along with the speed of 2v is 6.
What is kinetic energy?A kinetic energy is the engery generated by the movement or the motion of the moving objects. It is required for the acceleration of the moving body or the object.
Computation:
[tex]\begin{aligned}\dfrac{(\text{KE})_1}{(\text{KE})_2}&=\dfrac{\frac{1}{2}{m_1}\;{v_1^2}}{\frac{1}{2}{m_2}\;{v_2^2}}\\\\&=\dfrac{\frac{1}{2}{2m}\;{3v^2}}{\frac{1}{2}{3m}\;{v^2}}\\\\&=\dfrac{2\times9}{3}\\\\&=6\end{aligned}[/tex]

What x values are not included in the domain of the quotient of two functions
Any x value that makes the denominator equal to 0
Explanation:Rational Functions
The quotient of two functions can be rewritten as a rational function. All rational functions have discontinuities in the domain where the denominator equals 0. For this to make sense, remember that anything divided by 0 is undefined.
Examples
To show this idea, I will use the example [tex]\frac{x^3-2}{x+3}[/tex]. For this rational function or quotient of two functions, the x value -3 is not included in the domain. This is due to the fact that when x=-3, the denominator is equal to 0. Thus, the function is undefined at this value.
