Answer:
12 m/s
Explanation:
Hello
Kinetic energy is the energy associated with bodies that are in motion,it depends on the mass and speed of the body and is given by
[tex]E_{k} =\frac{m*v^{2} }{2}[/tex]
where m is the mass of the object , v is the velocity of the object and E is the kinetic energy
also
[tex]1 joule = \frac{Kg*m^{2} }{s^{2} }[/tex]
Now, isolating and replacing
[tex]E_{k} =\frac{m*v^{2} }{2}\\\frac{E_{k}}{m} =\frac{v^{2} }{2} \\v^{2} =\frac{2*E_{k} }{m}\\ v=\sqrt{\frac{2*E_{k} }{m}}\\\\ v=\sqrt{\frac{2*792\frac{kg*m^{2} }{s^{2} } }{11 kg}} \\v=\sqrt{144 \frac{m^{2} }{s^{2} } } \\v=12 \frac{m}{s}[/tex]
v=12 m/s
Have a great day
