Answer:
2440.24 J
Explanation:
Moment of inertia, I1 = 5 kg m^2
frequency, f1 = 3 rps
ω1 = 2 x π x f1 = 2 x π x 3 = 6 π rad/s
Moment of inertia, I2 = 2 kg m^2
Let the new frequency is f2.
ω2 = 2 x π x f2
here no external torque is applied, so the angular momentum remains constant.
I1 x ω1 = I2 x ω2
5 x 6 π = 2 x 2 x π x f2
f2 = 7.5 rps
ω2 = 2 x π x 7.5 = 15 π
Initial kinetic energy, K1 = 1/2 x I1 x ω1^2 = 0.5 x 5 x (6 π)² = 887.36 J
Final kinetic energy, K2 = 1/2 x I2 x ω2^2 = 0.5 x 3 x (15 π)² = 3327.6 J
Work done, W = Change in kinetic energy = 3327.6 - 887.36 = 2440.24 J

Thank you for your inspirational words. Thank you❤️
Alcohol overdose refers to an event whereby an individual consumes above the volume or amount of alcohol concentration which his system could bear. This could result all the responses listed in the option given except :
- Having a cool and clammy skin
Consuming excessive amount of alcohol usually result in abnormal function of some body system.
- Alcohol overdose usually result in unconscious feeling whereby the individual lacks adequate knowledge of his well being
- Having sensation of things which are not present is also a sign which shows that an individual is suffering from alcohol overdose.
- Having a cool and clammy skin is usually as a result of the temperature which an individual is exposed to.
Therefore, having a cool and clammy skin is usually not a sign of alcohol overdose.
