Respuesta :

The mass would be 4o, because 0.5 x 40=20 and 20 times 5 squared is 500.

Answer:

Mass of an object, m = 40 kg

Explanation:

It is given that,

Kinetic energy of an object, KE = 500 J

The object is moving with velocity of 5 m/s. We have to find the mass of an object. Kinetic energy is possessed due to moving body. Mathematically, it can be written as :

[tex]KE=\dfrac{1}{2}mv^2[/tex]

[tex]m=\dfrac{2\times KE}{v^2}[/tex]

[tex]m=\dfrac{2\times 500\ J}{(5\ m/s)^2}[/tex]

m = 40 kg

So, the mass of an object is 40 kg. Hence, this is the required solution.
