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 function named kineticEnergy that accepts an object’s mass (in kilograms) and velocity (in meters per second) as arguments. The function should return the amount of kinetic energy that the object has. Demonstrate the function by calling it in a

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:
KE = ½ m v2
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 function named
kineticEnergy that accepts an object's mass (in kilograms) and velocity (in meters per second) as
arguments. The function should return the amount of kinetic energy that the object has.
Demonstrate the function by calling it in a program that asks the user to enter values for mass and
velocity.

- Python XYZ store plans to give a festival discount to its customers. The store management has decided to give discount on the following criteria: Shopping Amount Discount Offered >=500 and <1000 5% >=1000 and <2000 8% >=2000 10% An additional discount of 5% is given to customers who are the members of the store. Create a program using user defined function that accepts the shopping amount as a parameter and calculates discount and net amount payable on the basis of the following conditions:Net Payable Amount = Total Shopping Amount – Discount.arrow_forwardC++ Visual 2019 A particular talent competition has five judges, each of whom awards a score between 0 and 10 to each performer. Fractional scores, such as 8.3, are allowed. A performer's final score is determined by dropping the highest and lowest score received, then averaging the three remaining scores. Write a program that uses this method to calculate a contestant's score. It should include the following functions: void getJudgeData() should ask the user for a judge's score, store it in a reference parameter variable, and validate it. This function should be called by main once for each of the five judges. void calcScore() should calculate and display the average of the three scores that remain after dropping the highest and lowest scores the performer received. This function should be called just once by main and should be passed the five scores. The last two functions, described below, should be called by calcScore, which uses the returned information to determine which of the…arrow_forwardFunction Name: leapYear Parameters: year - an nonnegative integer representing the year Test Cases: >>>leapYear(1996) The year 1996 is a leap year. Enjoy your extra day! >>>leapYear(1901) The year 1901 is not a leap year. Description: Write a function which calculates whether or not a given year is a leap year and has 366 days instead of 365. A general algorithm is as follows: 1. A year will be a leap year if it is divisible by 4 but not by 100. 2. If a year is divisible by 4 and by 100, it is not a leap year unless it is also divisible by 400. Years such as 1996, 1992, 1988 and so on are leap years because they are divisible by 4 but not by 100. For century years, the 400 rule is important. Century years (ex: 1900, 1800, 1700) are exactly divisible by 4 AND exactly divisible by 100. They are not divisible by 400 and are thus not leap years.
