An object has a kinetic energy of 12,000 J and a mass of 48.7 kg. Find the velocity of the object.I need help with this problem pls

Sagot :

Given:

The kinetic energy of the object is K = 12000 J.

The mass of the object is m = 48.7 kg

To find the velocity of the object.

Explanation:

The velocity of the object will be

[tex]\begin{gathered} K=\frac{1}{2}mv^2 \\ v=\sqrt{\frac{2K}{m}} \\ =\sqrt{\frac{2\times12000}{48.7}} \\ =22.199\text{ m/s} \end{gathered}[/tex]

Thus, the velocity of the object is 22.199 m/s.
