Answer:

0.14 kg

Step-by-step explanation:

The mass of the ball can be found by using the formula


m = \frac{2k}{ {v}^(2) } \\

v is the velocity

k is the kinetic energy

From the question we have


m = \frac{2(3.10)}{ {6.70}^(2) } = (6.20)/(44.89) \\ = 0.138115...

We have the final answer as

0.14 kg

Hope this helps you
