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.
