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 kinetic_energy 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. Write 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=12mv2The 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 kinetic_energy 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. Write a program that asks the user to enter values for mass andvelocity, then calls the kinetic_energy function to get the object’s kinetic energy.

The area of an arbitrary triangle can be computed using the formula
area = √(s(s–a)(s–b)(s–c))
where the square root is applied to the entire product and where a, b, and c are the lengths of the sides, and s is thesemiperimeter of the triangle given by the formula:
s = (a + b + c)/2
Write a void function named triangle that computes the area and perimeter (as well as the semiperimeter (which will be used to compute the area)of a triangle based on the length of the sides. The function should use five parametersand may call other functions.Make your function robust. Note that not all combinations of a, b, and c produce a triangle. Your function should produce correct resultsfor legal data and reasonable results for illegal combinations. Include in your submission a driver that repeatedly reads in 3 positive numbers thatare the sides of a triangle, and each time print out the sides and the area and perimeter calculated by the triangle function.

The data in the following chart was collected on a recent automobile trip: Write a C++ program that accepts a mileage and gallons value and calculates the miles pergallon (mpg) for that segment of the trip. The mpg is obtained as the difference in mileage between fill-ups divided by the number of gallons of gasoline used in the fill-up. b. Modify the program written for Exercise 9a to also compute and display the cumulative mpg after each fill-up. The cumulative mpg is calculated as the difference between the mileage at each fill-up and the mileage at the start of the trip divided by the sum of gallons used to that point in the trip.arrow_forward

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.

You may assume that this number is always between 0 and 25599 (inclusive of both). The function returns a formatted str containing an equivalent number of gallons, cups andtablespoons. The answer should use as many gallons, then cups as possible. For example:gct(312) would return '01g,03c,08t' as 312 tablespoons is equivalent to 1 gallon, 3 cups, and 8 tablespoons. Each of the output quantities (gallons, cups, tablespoons) should occupy two digits. If the values have less than two digits, they should be padded with leading zeroes. I.e., 2 cups is represented by '02c' .arrow_forward

Quantity discounts are given as follows: Quantity Discount 1-9 none, 10-19 12%, 20-49 23%, 50-99 34%, 100 or more 45%. Your function should accept the number of pants purchased as an argument and return the total cost after the discount.
