Title: Re: How much work does Juanita do if she uses a force of 40 newtons to pull 2 friends on a wagon for 32 meters? Post by: sptakqmc on Mar 24, 2023 To calculate the amount of work Juanita does, we need to use the formula:
Work = Force x Distance x Cosine(theta) Where: Force = 40 newtons (given) Distance = 32 meters (given) Cosine(theta) = Cosine of the angle between the direction of the force and the displacement. Since Juanita is pulling the wagon in a straight line, the angle between the force and displacement is 0 degrees, and cosine(0) = 1. Therefore: Work = 40 newtons x 32 meters x 1 Work = 1280 joules Therefore, Juanita does 1280 joules of work. |
