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.
How much work does Juanita do if she uses a force of 40 newtons to pull 2 friends on a wagon for 32 meters?
