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

1 Answer

2

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
