Answer:
The answer is 1.41 kg
Explanation:
The mass of an object given it's kinetic energy can be found by using the formula
[tex]m = \sqrt{ \frac{2KE}{v} } \\ [/tex]
where
m is the mass
v is the velocity
From the question we have
[tex]m = \sqrt{ \frac{2 \times 25}{25} } = \sqrt{ \frac{50}{25} } = \sqrt{2} \\ = 1.41421...[/tex]
We have the final answer as
1.41 kg
Hope this helps you
