Given:

The energy of the particle is E = 35950 J.

The velocity of the particle is v = 40 m/s

To find the mass of an object.

Explanation:

The mass can be calculated by the formula

[tex]\begin{gathered} E=\frac{1}{2}mv^2 \\ m=\frac{2E}{v^2} \end{gathered}[/tex]

On substituting the values, the mass will be

[tex]\begin{gathered} m\text{ = }\frac{2\times35950\text{ }kg\text{ m}^2\text{ /s}^2}{(40)^2\text{ m}^2\text{ /s}^2} \\ =44.94\text{ kg} \end{gathered}[/tex]

Thus, the mass of an object is 44.94 kg.
