Question

What is the kinetic energy of a 3kg ball that is rolling at 2 meters per second

Answer 1

6 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) * 3 * {2}^(2) \\ = (1)/(2) * 3 * 4 \\ = 3 * 2`

We have the final answer as

6 J

Hope this helps you
