The average rate at which the cable does work is 294,000 J/s.

The given parameters:

  • mass, m = 3000 kg
  • height, h = 200 m
  • time of motion, t = 20 s

The average rate at which the cable does work is calculated as follows;

[tex]P = \frac{E}{t} \\\\P = \frac{mgh}{t} \\\\P = \frac{3000 \times 9.8 \times 200}{20} \\\\P = 294,000 \ J/s[/tex]

Thus, the average rate at which the cable does work is 294,000 J/s.
