Answer:
To calculate the work being done by Sally, we need to use the formula:
Work = Force x Distance x cos(theta)
where:
Force = 10 N (the force required to lift the paintbrush)
Distance = 10 m (the distance Sally lifts the paintbrush)
theta = 0 degrees (since Sally is lifting the paintbrush straight up, the angle between the force and the direction of motion is 0 degrees)
So, the work done by Sally is:
Work = 10 N x 10 m x cos(0)
Work = 100 joules
Therefore, the joules of work being put out by Sally when she lifts the 10 N paintbrush at a distance of 10 meters is 100 joules.
