Question

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

Answer 1

Answer:

600 J

Explanation:

Given,

• Mass (m) = 12 kg
• Velocity (v) = 10 m/s

As we know,

Kinetic Energy,

• $E_{k} \: = \frac{1}{2} m {v}^{2}$

Therefore ,

Kinetic energy of the object is,

$= \frac{1}{2} \times 12 \: kg \times 10 \: m {s}^{ - 1} \times 10 \: m {s}^{ - 1}$

• (On dividing 12 by 2 we get 6)

= (6 × 10 × 10) J [As 'J' stands for 'joule']

= 600 J (Ans)
