What is the kinetic energy of a 3 kg object moving at 4 m/s?

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,

Here, KE is the kinetic energy of object.

Solving as,

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

kinetic energy of the object is 24 J

Explanation:

As we know that kinetic energy is given as

here we know that

m = 3 kg

v = 4 m/s

so we will have

so kinetic energy of the object is 24 J
