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.
