Questions & Step-by-Step Solutions

If a car does 600 J of work in moving a distance of 30 m, what is the average force exerted by the car? (2023)
  • Step 1: Identify the work done by the car, which is 600 Joules (J).
  • Step 2: Identify the distance the car moved, which is 30 meters (m).
  • Step 3: Use the formula for average force, which is Average Force (F) = Work (W) / Distance (d).
  • Step 4: Plug in the values: F = 600 J / 30 m.
  • Step 5: Calculate the average force: 600 divided by 30 equals 20.
  • Step 6: Conclude that the average force exerted by the car is 20 Newtons (N).
  • Work-Energy Principle – The relationship between work done, force applied, and distance moved.
  • Average Force Calculation – Understanding how to calculate average force using the formula F = W/d.
