To find the work done lifting the water.
Answer to Problem 6E
4900J work was done to lifting the water to a point 20 meters above the ground.
Explanation of Solution
Given information: The Bucket in Exercise 5 is hauled up more quickly so that there is still 10L (98N) of water when the bucket reaches the top.
Calculation:
You know from the previous problem that at 0 meters the bucket is 490N and that from problem 6 the bucket at 20 meters it has 98N. So the coordinates of the points are (0,490) and (20,98) and if you do a rough sketch of the points and find the equation the line it turns out to be
Hence, 5800J work was done lifting the water.
