Question

What is the kinetic energy of a car with a mass of 1200 kg and is traveling at 40 m/s?

Answer 1

9,600,000 J

Step-by-step explanation:

The kinetic energy of an object can be found by using the formula

`k = (1)/(2) m {v}^(2) \\`

m is the mass

v is the velocity

From the question we have

`k = (1)/(2) * 1200 * {40}^(2) \\ = 600 * 1600`

We have the final answer as

9,600,000 J

Hope this helps you
