Question

A car with a mass of 700 kg is moving with a speed of 20m/s.

Calculate the kinetic energy of the car.

Answer 1

The answer is 140,000 J

Step-by-step explanation:

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

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

where

m is the mass

v is the velocity

From the question we have

`KE = (1)/(2) * 700 * {20}^(2) \\ = 350 * 400`

We have the final answer as

140,000 J

Hope this helps you
