Answer:
To calculate the work being done by Lily, we need to use the formula:
Work = Force x Distance x cos(theta)
where:
Force = 2000 N (the force required to lift the ladder)
Distance = 8 m (the distance Lily lifts the ladder)
theta = 0 degrees (since Lily is lifting the ladder straight up, the angle between the force and the direction of motion is 0 degrees)
So, the work done by Lily is:
Work = 2000 N x 8 m x cos(0)
Work = 16000 joules
Therefore, the joules of work being put out by Lily when she lifts the 2000 N ladder above her head at a distance of 8 meters is 16000 joules.
