An engine develops a constant power of 40 kW . The total work done by the engine in 5 minutes is

Options

  1. A1.2 10^7 J
  2. B2.0 10^5 J
  3. C1.2 10^4 J
  4. D2.0 10^2 J

Correct answer

A. 1.2 10^7 J

Step-by-step solution

Given power P = 40 kW = 40 10^3 W Time t = 5 minutes = 5 60 s = 300 s Work done W = P t W = 40 10^3 300 W = 12 10^6 J = 1.2 10^7 J Answer: 1.2 10^7 J
