Question: If a car does 2000 J of work in moving a distance of 50 m, what is the average force exerted by the car? (2000)

Options:

  1. 40 N
  2. 50 N
  3. 60 N
  4. 30 N

Correct Answer: 40 N

Exam Year: 2000

Solution: 

Average Force (F) = Work done (W) / Distance (d) = 2000 J / 50 m = 40 N.

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 by the car? (2000)
  • Step 1: Identify the work done by the car, which is 2000 J (Joules).
  • Step 2: Identify the distance the car moved, which is 50 m (meters).
  • Step 3: Use the formula for average force, which is Average Force (F) = Work done (W) / Distance (d).
  • Step 4: Plug in the values: F = 2000 J / 50 m.
  • Step 5: Calculate the average force: 2000 J divided by 50 m equals 40 N (Newtons).
  • Work-Energy Principle – The relationship between work done, force, and distance, where work is defined as the product of force and distance in the direction of the force.
  • Average Force Calculation – Understanding how to calculate average force using the formula F = W/d, where W is work done and d is distance.
