Answer: The cat runs at a speed of 7.07 m/s
Explanation:
Kinetic energy is defined as the energy which is possessed due to its motion.
It is also defined as the half of the product of mass of the object and square of the velocity of the object.
Mathematically,
[tex]E_K=\frac{1}{2}mv^2[/tex]
where,
[tex]E_K[/tex] = kinetic energy of cat = 150 J
m = mass of the cat = 6.0 kg
v = velocity of cat
Putting values in above equation, we get:
[tex]150J=\frac{1}{2}\times 6.0\times (v)^2\\\\v=\sqrt{\frac{2\times 150}{6}}=7.07m/s[/tex]
Hence, the cat runs at a speed of 7.07 m/s
