Questions & Step-by-Step Solutions

A car engine does 3000 J of work in 5 seconds. What is the average power output of the engine?
  • Step 1: Identify the work done by the car engine, which is 3000 Joules (J).
  • Step 2: Identify the time taken for the work, which is 5 seconds (s).
  • Step 3: Use the formula for power, which is P = W/t, where P is power, W is work, and t is time.
  • Step 4: Substitute the values into the formula: P = 3000 J / 5 s.
  • Step 5: Calculate the result: 3000 J divided by 5 s equals 600 Watts (W).
  • Step 6: Conclude that the average power output of the engine is 600 W.
  • Power Calculation – Understanding the relationship between work, time, and power, specifically using the formula P = W/t.
