When transporting cargo, a dump truck develops a power of 60 kW, which work does it within 2 minutes.

To determine the work performed by the used dump truck when transporting cargo, we use the formula: A = N * t.

Values of variables: N – power of the used dump truck (N = 60 kW = 60 * 10 ^ 3 W); t – time of work execution (t = 2 min; in SI t = 120 s).

Let’s calculate: A = N * t = 60 * 10 ^ 3 * 120 = 7.2 * 10 ^ 6 J = 7.2 MJ.

Answer: When transporting cargo, the used dump truck performed work of 7.2 MJ.
