Answer:

W = 3.15 · 10⁶ J  

Explanation:

We know that power is calculated using the formula:

  • P = W/t
  • where P = power (W), W = work (J), and t = time (s)  

We can derive a formula for work using this formula by multiplying t to both sides of the equation.

  • W = Pt

Let's convert 15 kW to W.

  • 15 kW → 15,000 W

Let's convert 3.5 min to s.

  • 3.5 min → 210 s

Substitute these values into the formula for work and solve for W.

  • W = Pt
  • W = (15,000 W) · (210 s)
  • W = 3,150,000 J  
  • W = 3.15 · 10⁶ J  

This is the amount of work done by a 15 kW engine in 3.5 minutes.
