Answer:
The answer is 500 kg
Explanation:
The mass of the object can be found by using the formula
[tex]m = \frac{2KE}{ {v}^{2} } \\ [/tex]
v is the velocity
KE is the kinetic energy
From the question we have
[tex]m = \frac{2 \times 100000}{ {20}^{2} } = \frac{200000 }{400} = \frac{2000}{4} \\ [/tex]
We have the final answer as
500 kg
Hope this helps you
