Answer:

kinetic energy of the object is 24 J

Explanation:

As we know that kinetic energy is given as

[tex]K = \frac{1}{2}mv^2[/tex]

here we know that

m = 3 kg

v = 4 m/s

so we will have

[tex]k = \frac{1}{2}(3)(4^2)[/tex]

[tex]k = 24 J[/tex]

so kinetic energy of the object is 24 J

The kinetic energy of the object is 24 J.

Given data:

The mass of object is, m = 3 kg.

The speed of the object is, v = 4 m/s.

The kinetic energy of an object is the energy possessed by any object due to its motion, which is mathematically expressed as half multiplied by mass and square of the speed of object.

That is,

[tex]KE = \dfrac{1}{2}mv^{2}[/tex]

Here, KE is the kinetic energy of object.

Solving as,

[tex]KE = \dfrac{1}{2} \times m \times v^{2}\\\\KE = \dfrac{1}{2} \times 3 \times 4^{2}\\\\KE = 24 \;\rm J[/tex]

Thus, we can conclude that the kinetic energy of the object is 24 J.
