Question

What is the kinetic energy of an object that has a mass of 12 kilograms and moves with a velocity of 10 m/s?

Answer 1

1/2mv^2

1/2x12x10^2=600J

The kinetic energy is 600J

Answer 2

Answer:

The kinetic energy of the object is 600 J

Explanation:

It is given that,

Mass of the object, m = 12 kg

Velocity of the object, v = 10 m/s

Kinetic energy of the object is given by :

$E=\dfrac{1}{2}mv^2$

$E=\dfrac{1}{2}\times 12\times (10)^2$

E = 600 J

So, the kinetic energy of the object is 600 J. Hence, this is the required solution.
