Answer:

The particle's velocity is calculated to be 2 m/s,

Explanation:

Kinetic energy refers to the energy an object possesses due to its movement. The formula for kinetic energy is:

$K.E=\frac{1}{2}mv^2$

Where:

m = the mass of the object

v = the object's velocity

A particle with mass m has a kinetic energy that is double its mass.

$K.E=2m$

$2m=\frac{1}{2}mv^2$

$v^2=\frac{4}{1}$

$v=2$

Since the velocity is measured in m/s, we determine that the particle's speed is 2 m/s.
