Question 8 of 35

A car has a mass of 1000 kg and is travelling at a speed of 26 m/s. Calculate the kinetic energy of the
car. Use the word equation below to help you.
kinetic energy = 0.5 x mass x (speed)?

Answer 1

338,000 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) * 1000 * {26}^(2) \\ = 500 * 676 \\ = 338000`

We have the final answer as

338,000 J

Hope this helps you
