Final answer:
The work done by a student carrying a heavy backpack weighing 252 N over a distance of 365 m horizontally is 91980 Joules.
Step-by-step explanation:
When a student walks a distance of 365 m with a heavy backpack that weighs 252 N, the amount of work done is calculated using the formula Work = Force x Distance x cos(θ), where θ is the angle between the force and the direction of motion.
Since the student applies the force in the same direction as they are moving (horizontally), the angle is 0 degrees, and cos(0) is 1. Therefore, the work done is simply the product of the force (weight of the backpack) and the distance.
The calculation for the given situation is 252 N (force) × 365 m (distance) × cos(0°), which yields Work = 252 N × 365 m = 91980 Joules. This means the student does 91980 Joules of work by carrying the backpack to their house.
