Work is done by a force acting on a mass when that mass is displaced (moved).
Basically, more work is required to move a mass through a greater distance, similarly more work is required to move a greater mass though the same distance.
Providing all other things are equal, if the same box is moved through a distance of two metres you do more work than moving the box through one metre.

the job gets easier the higher you lift the object
vf = sqrt(vo2 + 2a(X - Xo)) in this casevf = sqrt(0+2*9.8(Height of shelf)

What is the question?
0 / 200 = 0 meters.
The height of the shelf can be calculated using the formula: work done = force x distance. In this case, the work done is 40 J, the force is 10 N, so the distance (height of the shelf) can be calculated as 40 J / 10 N = 4 meters.

There are seven books on the floor. Let x be the number of books on the floor. The number of books on the shelf is 2 + 3x. From the information given, 3x + 2 = number of books on the shelf. Substitute x=7 into 3x + 2 to find the answer. So, there are 23 books on the shelf.

You would probably be better off with it sitting on the floor, as it could possibly vibrate during heavy periods of bass sound if placed on a shelf. If you wanted to place it on a shelf, you could always reduce the bass output, but in my opinion, this would negate the reason for having a sub-woofer in the first place, and could lead to the system sounding rather tinny.
The average width of the continental shelf is about 80 km or 50 miles. The Shelf descends steeply down to the continental rise before reaching the ocean floor.
THE SHELF
Benthos can be anywhere as long as they are on the ocean floor, from the continenal shelf to the abyssal plain.
