Question

A person lifts a 11.1 kg box of bricks a vertical distance of 1.40 m and then carries the box horizontally a distance of 8.00 m. How much work is done by the person in the process?

Answer 1

Step-by-step explanation:

Assuming that the person is the only force applying work to the box, the total work done by the person is 993.4 J. This is calculated by multiplying the force of gravity (98.1 N) with the vertical distance (1.40 m) to obtain 137.4 J, and then adding the work done in carrying the box horizontally (8.00 m × 98.1 N = 756.8 J). Therefore, the total work done is 137.4 J + 756.8 J = 993.4 J.
