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.
