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

The measures give the description of the shape and the whisker plot from the data. The median is always placed in the middle of the center.
<h3>What is a graph?</h3>
A graph is the diagrammatical representation of the data or information set that are illustrated in the form of vertical and horizontal coordinates.
The data given shows:
- Mean = 39,500
- Median = 20000
- Mode = 23000
- Minimum = 15,000
- Maximum = 255000
The whisker plot and the box shape are attached as an image below.
From the image, it can be seen that whiskers are at the right and left of the box, and the box initiates from the lower quartile to the upper quartile.
The median of the data is at the middle, the maximum is at the end of the right whisker, and the minimum is at the end of the left whisker.
