Question

A young work crew is trying to quickly finish some touch-up painting to complete a job. Rather than setting up a secure work area, they decide to try a shortcut. Worker A will hold the far end of a 8.98 m work plank which weighs 112 N and is secured with a hinge on the opposite end. Worker B will stand on the plank 4.33 m from worker A.
