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:
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

Herbert’s Home Repair estimates each job cost as the cost of materials plus $35 per hour while on the job, plus $12 per hour for travel time to the job site.
The main() method prompts the user for the name of a job (for example, Smith bathroom remodel), the cost of materials, the number of hours of work required, and the number of hours travel time.
Pass the numeric data to a method that computes an estimate for the job and returns the computed value to the main() method which displays the job name and estimated price.

When an object is falling because of gravity, the following formula can be used to determine the distance the object falls in a specific time period:
d = ½ gt2
The variables in the formula are as follows: d is the distance in meters, g is 9.8, and t is the amount of time, in seconds, that the object has been falling.
5.3.1. Create a method: FallingDistance
Parameters: t, object’s falling time (in seconds) t may or may not be an integer value!
Return value: the distance, in meters, that the object has fallen during that time interval
Calculations: Use Math.Pow() to calculated the square in the formula
5.3.2. Demonstrate the method by calling it from a loop that passes the values 1 through 20 as arguments, and displays each returned value.
Sample output lines:
. . .
t = 5, d = 122.5
. . .
t = 10, d = 490
. . .
Your output should have lines for t=1, t=2, t=3, . . . t=20.

One such technique is known as theBabylonian method. It approximates the square root of a number, n, by repeatedlyperforming a calculation using the following formula: nextGuess = (lastGuess + n / lastGuess) / 2 When nextGuess and lastGuess are almost identical, nextGuess is theapproximated square root. The initial guess can be any positive value (e.g., 1).This value will be the starting value for lastGuess. If the difference betweennextGuess and lastGuess is less than a very small number, such as 0.0001,you can claim that nextGuess is the approximated square root of n. If not, next-Guess becomes lastGuess and the approximation process continues.

These methods ask the user to input the expiration year and month of their credit card. Each method should contain a loop inside the method so the code repeats until a valid month or year is entered by the user. If the user enters an invalid year or month, print an error message and ask them to try again. The readMonth(int) method reads in the month as a number. A valid month is any number between 1 and 12 (inclusive). A valid year is 2022 or later. readCreditCardNumber() method Complete the readCreditCardNumber() method.

Write a method named isPrime, which takes an integer as an argument and returns true if the argument is a prime number, or false otherwise. Demonstrate the method in a complete program. Tip: Recall that the % operator divides one number by another, and returns the remainder of the division. In an expression such as num1 % num2, the % operator will return 0 if num1 is evenly divisible by num2.
