Questions & Step-by-Step Solutions
A car does 5000 J of work in moving a distance of 100 m. What is the average force exerted by the car? (2023)
Step 1: Understand that work done (in joules) is equal to the force applied (in newtons) multiplied by the distance (in meters) over which the force is applied.
Step 2: Write down the formula for average force: Average Force = Work done / Distance.
Step 3: Substitute the values into the formula: Work done = 5000 J and Distance = 100 m.
Step 4: Calculate the average force: Average Force = 5000 J / 100 m.
Step 5: Perform the division: 5000 divided by 100 equals 50.
Step 6: Conclude that the average force exerted by the car is 50 N.
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: Average Force = Work done / Distance.
