A student, while moving out of his old apartment, is loading a rented moving truck using a ramp which is at a rather steep angle of 28.0 degrees above the horizontal; the ramp is 2.70 m long. At one point in the loading process he drags a loaded suitcase of mass 25.50 kg up the full length of the ramp. The wheels on the old suitcase have long since ceased to function properly, so that the effective coefficient of kinetic friction between the suitcase and the inclined ramp is 0.260. The old suitcase has a strap attached to one corner, and the student does the dragging by pulling on this strap and running up the ramp (he is in a hurry) so that he and the suitcase speed up while going up the ramp. It turns out the the student is able to maintain a tension of 188.0 N during his pull, and the angle between the strap and the incline is 19.0 degrees(the strap direction is 19.0 degrees higher than the incline angle).
A.How much work is done on the suitcase by the tension force during the pull up the ramp?
B.How much work is done by the force of gravity on the suitcase by the Earth during the pull up the ramp?
D.How much work is done by the frictional force on the suitcase by the ramp during the pull up the ramp?
E.As a result of the pull up the incline, what is the increase in the thermal energy present in the suitcase and in the surface of the ramp?
F.What is the change in the kinetic energy of the suitcase as a result of the pull up the incline?

2.How does Prolog try to resolve our Queries?
a.The programmer specifies the algorithmic approach, performance is all in the hands of how clever the programmer writes their algorithms.
b.The language applies some AI to our query and precludes obviously false information.
c.Row by agonizing row. There is nothing particularly clever about the solve, it just brute forces its way through the data looking for resolutions.

Write an IterativeMergeSort function given these parameters and following the prompt
IterativeMergeSort(vector<int> v, int low, int high)
IterativeMergeSort
In-place sorting refers to sorting that does not require extra memory arrays. For
example, QuickSort performs partitioning operations by repeating a swapping operation on two
data items in a given array. This does not require an extra array.
We can improve the performance of MergeSort by utilizing a non-recursive method and
using only one additional array (instead of one array on each recursive call). In this improved
version of MergeSort,
IterativeMergeSort
, one would merge data from the original array into
the additional array and
alternatively
copy back and forth between the original and the
additional temporary array.
Please re-read the last sentence as it is critical to the grading of
the lab.
For the IterativeMergeSort we still need to allow data items to be copied between the
original and this additional array as many times as O(
log
n). However, given the iterative nature
we are not building up state on the stack.

CASE STUDY
A man worked successfully until he retired at age sixty. He was blessed with an appreciable bulk amount as retirement package. After receiving his pension proceeds, he decided to invest it in a sawmill business, on a plot of land in front of his residence in a typical residential area. He put up a structure for the intended business, procured the necessary machines, installed them and employed some youthful workers within his locality to commence business. The business started to pick up gradually and after some time, the business could be described as encouraging. However, at the peak of the business, complaints from his locality became a major issue which was not heeded to by the owner of the sawmill business. Their concerns got to the authorities and the officials of the Environmental Protection Agency (EPA). The EPA, initially, issued a warning notice to stop operation which was not obeyed. The subsequent action of the EPA was to close down the sawmill business. This action had an adverse effect on the health of the business owner because he had invested all this pension benefits into the business and this, led to his untimely demise.
