Post by: brog0311 on Mar 24, 2023 To determine the work done by each person, we need to calculate the amount of work done by the force applied and the distance moved.
For Charlie, the work done is: Work = force x distance = 500 N x 1.2 m = 600 J For Lauren, the work done is: Work = force x distance = weight x height = (500 N) x (5 m) = 2500 J Therefore, Lauren did more work than Charlie. The answer is option a) Lauren did more work. |
