how much work is required to lift a 10 newton weight from 4.0 meters to 40.0 meters above the surface of earth

360 Joules

Work = Force * Distance * cosine Theta

work = -10N * 36m * cos(180)
work = -10N * 36m * -1
work= 360J

3.6 x 10^2 J

To calculate the work required to lift a weight, you can use the formula:

Work = Force × Distance

Given that the weight to be lifted is 10 newtons and the height is changed from 4.0 meters to 40.0 meters, we can substitute these values into the formula.

First, determine the distance being traveled:

Distance = final height - initial height
Distance = 40.0 m - 4.0 m
Distance = 36.0 m

Now substitute the values into the work formula:

Work = 10 N × 36.0 m
Work = 360 joules

Therefore, the work required to lift the 10 newton weight from 4.0 meters to 40.0 meters above the surface of the earth is 360 joules.
