Question

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

Answer 1

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.

Step-by-step explanation:

The velocity of the object will be

`\begin{gathered} K=(1)/(2)mv^2 \\ v=\sqrt{(2K)/(m)} \\ =\sqrt{(2*12000)/(48.7)} \\ =22.199\text{ m/s} \end{gathered}`

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