A golfer hits a shot to a green that is elevated 2.50 m above the point where the ball is struck. The ball leaves the club at a speed of 17.3 m/s at an angle of 43.0˚ above the horizontal. It rises to its maximum height and then falls down to the green. Ignoring air resistance, find the speed of the ball just before it lands.

create code for an address book console program in C++ that:

1. Uses a basic array in the main program to hold multiple Record class objects.
2. A Record class is to be constructed with the following member variables:
   1. Record number,
   2. first name,
   3. last name,
   4. age, and
   5. telephone number.
3. The Record class must have a custom constructor that initializes the member variables.
4. The Record class declaration is to be separated from the Record class implementation and these are to be placed in .h and .cpp files respectively.
5. The program should have a perpetual menu that allows a choice of:
   1. Input information into an record,
   2. Display all information in all records, and
   3. Exit the program.
6. The program should hold 10 records at the minimum.

2. Another Type of Employee

The files Firm.java, Staff.java, StaffMember.java, Volunteer.java, Employee.java, Executive.java, and

Hourly.java are from Listings 10.1 - 10.7 in the text. The program illustrates inheritance and polymorphism.

In this exercise you will add one more employee type to the class hierarchy (see Figure 9.1 in the text).

The employee will be one that is an hourly employee but also earns a commission on sales. Hence the class, which we’ll name Commission, will be derived from the Hourly class.

Write a class named Commission with the following features:

• It extends the Hourly class.
• It has two instance variables (in addition to those inherited): one is the total sales the employee has made (type double) and the second is the commission rate for the employee (the commission rate will be type double and will represent the percent (in decimal form) commission the employee earns on sales (so .2 would mean the employee earns 20% commission on sales)).
• The constructor takes 6 parameters: the first 5 are the same as for Hourly (name, address, phone number, social security number, hourly pay rate) and the 6th is the commission rate for the employee. The constructor should call the constructor of the parent class with the first 5 parameters then use the 6th to set the commission rate.
• One additional method is needed: public void addSales (double totalSales) that adds the parameter to the instance variable representing total sales.
• The pay method must call the pay method of the parent class to compute the pay for hours worked then add to that the pay from commission on sales. (See the pay method in the Executive class.) The total sales should be set back to 0 (note: you don’t need to set the hours Worked back to 0—why not?).
• The toString method needs to call the toString method of the parent class then add the total sales to that.

To test your class, update Staff.java as follows:

• Increase the size of the array to 8.
• Add two commissioned employees to the staffList—make up your own names, addresses, phone numbers and social security numbers. Have one of the employees earn $12.00 per hour and 20% commission and the other one earn $14.75 per hour and 15% commission.
• For the first additional employee you added, put the hours worked at 35 and the total sales $400; for the second, put the hours at 40 and the sales at $950.

Compile and run the program. Make sure it is working properly.

Hello, I need to come up with the java code for a program that looks at bank Account ID's and checks if it is in the frame work of Letter followed by 4 numbers, so for example "A001". I need it to be its own method, named checkAccountID() that passes the accountID as an argument to check if it is in that framework of one letter followed by 4 numbers. Any ideas?

a) An iron sulfide contains 36.5% S by mass. The iron sulfide is heated in an atmosphere of pure oxygen, which produces SO2(g) and an iron oxide containing 27.6% O by mass.

Write a balanced equation for the reaction.

If 1.0 kg of the iron sulfide reacts with excess oxygen, what is the theoretical yield of the iron oxide?

b) In the manufacture of Portland cement, limestone (CaCO3(s)) is decomposed into lime (CaO(s)) and CO2(g), in a kiln. Use data from Appendix C in your textbook to calculate how much heat is required to decompose 2.70 × 103 kg of limestone. (Assume that the heats of reaction are temperature independent.)

The telescopes on some commercial surveillance satellites can resolve objects on the ground as small as 92 cm across (see Google Earth), and the telescopes on military surveillance satellites reportedly can resolve objects as small as 12 cm across. Assume first that object resolution is determined entirely by Rayleigh's criterion and is not degraded by turbulence in the atmosphere. Also assume that the satellites are at a typical altitude of 408 km and that the wavelength of visible light is 537 nm. What would be the required diameter of the telescope aperture for (a) 92 cm resolution and (b) 12 cm resolution? (c) Now, considering that turbulence is certain to degrade resolution and that the aperture diameter of the Hubble Space Telescope is 2.4 m, what can you say about the answer to (b), i.e. is the military surveillance resolution accomplished?
