Two automobiles with equal mass approach an intersection.  One vehicle is traveling eastward and the other vehicle is traveling northward.  The vehicles collide and stick together. After impact they travel on the road and then travel on a gravel covered shoulder until both cars stop. Only the northward bound vehicle left skid marks at an angle of 55 degrees north of east.  A police officer posted at the intersection clocked the eastward vehicle at 29 mph before impact. The northward bound car skid on the road for 25 ft and continued to skid on the gravel covered shoulder.  What is the total distance, in feet, the two cars traveled after the collision? Assume u_s = 0.96 and u_k = 0.85 for the road and u_s = 0.74 and u_k = 0.65 for the shoulder.

For Python:

In this assignment you are asked to write a Python program to determine the Academic Standing of a studentbased on their CGPA. The program should do the following:

1. Prompt the user to enter his name.
2. Prompt the user to enter his major.
3. Prompt the user to enter grades for 3 subjects (A, B, C, D, F).
4. Calculate the CGPA of the student.

To calculate CGPA use the formula:

CGPA = (quality points * credit hours) / credit hours

            Each subject is worth of 3 credit hours.

5. Once you have calculated the CGPA determine their Academic Standing based on the table below.

6. The output should be in the following format:

Enter student’s name:   

Enter student’s major:

Enter the grade for subject1 (A, B, C, D, F):

Enter the grade for subject2 (A, B, C, D, F)::

Enter the grade for subject3 (A, B, C, D, F)::

#Skip a couple of lines

Student Name:              #All letters should be in uppercase

Major:                          #The major should be displayed in title case

CGPA:

Academic Standing:

The grades entered should belong to the set {A, B, C, D, F}.  After the prompt, check to be sure they are one of those.  Print (display) an error message if they are not and do not prompt the user for the grades again. The program ends.

Sample Output:

Enter student’s name: james smith

Enter student’s major: Electrical Engineering

Enter the grade for subject1 (A, B, C, D, F): A

Enter the grade for subject2 (A, B, C, D, F): B

Enter the grade for subject3 (A, B, C, D, F): A

Student Name: JAMES SMITH

Major: Electrical Engineering

CGPA: 3.76

Academic Standing: Good

Company Zeta bought new office furniture in the year 2000. The purchase cost was 97972 dollars and in addition it had to spend 13926 dollars for installation. The furniture has been in use since April 21st, 2000. Zeta forecasted that in 2015 the office furniture would have a net salvage value of $1000. Using the US Accelerated Depreciation Schedule, estimate the value of depreciation recorded in the accounting books in the year 2004 if the company decided to sell the furniture on June 5th (of 2004).
