Answer:
72 J
Explanation:
Total kinetic energy will be tge sum of rotational and translational energy.
Rotational kinetic energy is given by 
where I is moment of inertia which is given by 
and here m is mass, r is radius. Also, 
hence making \omega the subject then 
where v is the velocity.
Rotational kinetic energy=
This is same as the formula for translational kinetic energy which is given by 
Therefore, total kinetic energy= 
Substituting m with 2 kg and v with 6 m/s then total energy will be

Answer:
Sometimes atoms gain or lose electrons. The atom then loses or gains a "negative" charge. These atoms are then called ions. Positive Ion - Occurs when an atom loses an electron negative charge it has more protons than electrons.
