To determine the work done when a force is applied to an object, the formula to use is work = force × distance. In this case, Lindsay applied a force of 5 newtons over a distance of 16 meters.
Using the formula, the calculation is as follows:
Work = Force × Distance
Work = 5 N × 16 m
Work = 80 joules
Thus, the correct calculation shows that Lindsay did 80 joules of work on the shopping cart. This aligns with the physical concept of work, which is defined as the product of the force and the distance over which that force is applied in the same direction.
The incorrect answer indicates a misunderstanding, possibly from miscalculating the force and distance or utilizing the formula incorrectly. Understanding the relationship between force, distance, and work is crucial in physics, especially in practical applications like this one.
