Java Program, which determines the distance travelled by a projectile

Write a Program in Java, which determines the distance travelled by a projectile (launched from the ground) given: 1. The velocity at launch (u), and 2.The launch angle (angle of elevation) above the horizontal (A). The program should consist of two files: Launch.java and LaunchApp.java (application). Assume the following: 1. The angle of elevation is given in degrees and is in the range of 0 to 90. 2. Start velocity is given as a positive number. 3. Gravity (g) is equivalent to 10m/s ^ 2. 4. Ignore air resistance. Note also that to solve the above we must carry out the following steps: 1. Calculate the vertical and horizontal components of u (the l... click for more

C ++ Exercise

I need a C++ program that reads students’ names followed by their test scores. The program should output each student’s name followed by the test scores and the relevant grade. It should also find and print the highest test score and the name of the students having the highest test score. Student data should be stored in a struct variable of the type studentType, which has four components: studentFName and studentLName of the type string, testScore of the type int (testScore is between 0 and 100), and grade of the type char. My class has 20 students. Use an array of 20 components of the type studentType. The program must contain at least the following functions: a.) A funct... click for more

Input two sides of a rectangle, program should output the area and perimeter

When you input two sides of a rectangle, your Java-program should output the area and perimeter of that rectangle (use the template code attached). The program should consist of two java files, Rectangle.java and RectangleApp.java. Comment the code.

Input two strings representing your first and last names, have your Java program output your initials

When you input two strings representing your first and last names, have your program output your initials. The program should consist of two files, Initials.java and InitialsApp.java. Comment the code.
