Answer:
162 Joules
Step-by-step explanation:
Remember, the equation for the kinetic energy of an object is:
[tex]K=\frac{1}{2}mv^{2}[/tex]
where m is the mass of the object in kg (kilograms), v is the velocity of the object in m/s (meters per second), and K is the kinetic energy of the object in J (joules).
We are given that the cat's mass is 4 kg. We will use this for m. We are also given that the cat is moving at 9 m/s. This would be it's speed. We can use this for velocity, or v. Plugging in we get:
[tex]K=\frac{1}{2}mv^{2}=\frac{1}{2}(4)(9)^{2}=(2)(81)=162[/tex]
So K, or the kinetic energy, would be 162J.
I hope you find my answer and explanation to be helpful. Happy studying.
