Answer:
0.14 kg
Explanation:
The mass of the ball can be found by using the formula
[tex]m = \frac{2k}{ {v}^{2} } \\ [/tex]
v is the velocity
k is the kinetic energy
From the question we have
[tex]m = \frac{2(3.10)}{ {6.70}^{2} } = \frac{6.20}{44.89} \\ = 0.138115...[/tex]
We have the final answer as
0.14 kg
Hope this helps you
