Question

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

Answer 1

Answer:

6 J

Explanation:

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

$k = \frac{1}{2} m {v}^{2}$

m is the mass

v is the velocity

From the question we have

$k = \frac{1}{2} \times 3 \times {2}^{2} \\ = \frac{1}{2} \times 3 \times 4 \\ = 3 \times 2$

We have the final answer as

6 J

Hope this helps you
