| These tasks: A (the work performed by the indicated weightlifter) = 5 kJ = 5 * 10 ^ 3 J; t (time spent by the weightlifter) = 2 s.

To calculate the power value of the specified weight lifter, apply the formula: N = A / t.

Calculation: N = A / t = 5 * 10 ^ 3/2 = 2.5 * 10 ^ 3 W.

Answer: The power of the indicated weightlifter was 2.5 kW.
