Questions & Step-by-Step Solutions
If a car does 3000 J of work in moving a distance of 150 m, what is the average force exerted by the car? (2023)
Step 1: Understand that work is the energy used when a force moves an object over a distance.
Step 2: Identify the formula to find average force, which is Average Force = Work / Distance.
Step 3: Plug in the values from the question: Work = 3000 J and Distance = 150 m.
Step 4: Calculate the average force by dividing 3000 J by 150 m.
Step 5: Perform the calculation: 3000 J / 150 m = 20 N.
Step 6: Conclude that the average force exerted by the car is 20 N.
Work-Energy Principle – The relationship between work done, force applied, and distance moved, where work is defined as the product of force and distance.
Average Force Calculation – Understanding how to calculate average force using the formula: Average Force = Work / Distance.
