Questions & Step-by-Step Solutions

If a car does 2000 J of work in moving a distance of 50 m, what is the average force exerted? (2023)
  • Step 1: Understand that work is defined as the energy transferred when a force moves an object over a distance.
  • Step 2: Identify the formula for average force, which is Average Force = Work / Distance.
  • Step 3: Plug in the values from the question: Work = 2000 J and Distance = 50 m.
  • Step 4: Calculate the average force by dividing the work by the distance: 2000 J / 50 m.
  • Step 5: Perform the division: 2000 divided by 50 equals 40.
  • Step 6: Conclude that the average force exerted is 40 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: Force = Work / Distance.
