Answer: 3.464 m/s

Explanation:

The Kinetic Energy [tex]K[/tex] is mathematically expressed as:

[tex]K=\frac{1}{2}mV^{2}[/tex]   (1)

Where:

[tex]K=3J[/tex]

[tex]m=0.5kg[/tex] is the mass of the body

[tex]V[/tex] its velocity

Rewritting (1):

[tex]3J=\frac{1}{2}(0.5kg)V^{2}[/tex]   (2)

Isolating [tex]V[/tex]:

[tex]V=\sqrt{\frac{6J}{0.5kg}}[/tex]   (3)

Finally:

[tex]V=3.464m/s[/tex]
