Question

What is the kinetic energy of a 125 kg cart that is moving at a speed of 2 m/s?

(i suck at science like wth when did we start using math in science)

Answer 1

250 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) * 125 * {2}^(2) \\ = (1)/(2) * 125 *4 \\ = 125 * 2`

We have the final answer as

250 J

Hope this helps you
