Textbook Question

Chapter 5, Problem 12PC

Kinetic Energy

In physics, an object that is in motion is said to have kinetic energy. The following formula can be used to determine a moving object’s kinetic energy:

K E = 1 2 m v 2

The variables in the formula are as follows: KE is the kinetic energy, m is the object’s mass in kilograms, and v is the object’s velocity, in meters per second.

Write a method named kineticEnergy that accepts an object’s mass (in kilograms) and velocity (in meters per second) as arguments. The method should return the amount of kinetic energy that the object has. Demonstrate the method by calling it in a program that asks the user to enter values for mass and velocity.

Although color television was not added to the industry standard until 1956, CBS had been broadcasting selected special events in color as early as 1950. Question 1 options: True False Two key factors in creating the Network Era of American television were the FCC licensing freeze and ______________. Question 4 options: The Quiz Show Scandals Habitual Viewing Operation Frontal Lobes Drop-In Viewing Least Objectionable Programming was designed to embrace the public service-oriented vision of using television to elevate mass culture and enrich viewers. Question 6 options: True False By the end of the 1950s, all three remaining networks (NBC, CBS, & ABC) were broadcasting their entire nightly programming schedule in full color. Question 9 options: True False

7. See the code below and solve the following. public class Test { public static void main(String[] args) { int result = 0; } result = fn(2,3); System.out.println("The result is: + result); // fn(x, 1) = x // fn(x, y) = fn(x, y-1) + 2, when y>1 public static int fn(int x, int y) { if (x <= 1) return x; else return fn(x, y-1) + 2; } } 7-1. This program has a bug that leads to infinite recursion. Modify fn(int x, int y) method to fix the problem. (2 point) 7-2. Manually trace the recursive call, fn(2,3) and show the output (step by step). (2 point) 7-3. Can you identify the Base Case in recursive method fn(int x, int y)? (1 point)

6. See the code below and solve the following. import java.io.*; public class DataStream { } public static void main(String[] args) } DataOutputStream output = new DataOutputStream(new FileOutputStream("temp.dat")); output.writeUTF("Book1"); output.writeInt(85); output.writeUTF("Book2"); output.writeInt(125); output.writeUTF("Book3"); output.writeInt(70); output.close(); // ToDo: Read all data from temp.dat and print the data to the standard output (monitor) 6-1. This program has a compile error, and the message is “Unhandled exception type FileNotFoundException". How do you fix this error? (1 point) 6-2. Is FileNotFoundException a checked exception or an unchecked exception? (1 point) 6-3. What is the difference between checked exception and unchecked exception? (1 point) 6-4. Please complete the above program by reading all data from temp.dat and print the data to the standard output (monitor) by using System.out.print, System.out.println or System.out.printf method.
