An ice skater has a moment of inertia of 5. 0 kg∙m2 when her arms are outstretched. At this time she is spinning at 3. 0 revolut
Sindrei [870]

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

Citrus2011 [14]

Based on the excerpt, President Jimmy Carter made reference to the meeting he had with various leaders on the energy crisis.

<h3>What is a state crisis?</h3>

A state crisis can be defined as any form of event that has the potential of causing an unstable and dangerous situation across a country, thereby, adversely affecting the people that are living within it.

In this scenario, the United States of America had an energy crisis while Jimmy Carter was the president. Thus, President Jimmy Carter gave a speech on the 15th of July, 1979 to address the citizens of the United States of America on their energy crisis through a live TV broadcast.
