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

- (Civil eng.) Write an assignment statement to calculate the linear expansion in a steel beam as a function of temperature increase. The formula for linear expansion, l, is as follows: l=l0(1+(TfT0)) l0isthelengthofthebeamattemperatureT0.isthecoefficientoflinearexpansion.Tfisthefinaltemperatureofthebeam.arrow_forward(General math) a. Write a function named rightTriangle() that accepts the lengths of two sides of a right triangle as the arguments a and b. The subroutine should determine and return the hypotenuse, c, of the triangle. (Hint:UsePythagorastheorem,c2=a2+b2.) b. Include the function written for Exercise 4a in a working program. The main() function should call rightTriangle() correctly and display the value the function returns.arrow_forward(Physics) Buoyancy is the upward force a liquid exerts on a submerged object, as shown in Figure 6.9. The buoyancy force is given by this formula: B=pgV Bisthebuoyancyforce( lbforN).isthefluiddensity( slug/f t 3 orkg/ m 3 ).gistheaccelerationcausedbygravity( 32.2ft/se c 2 or9.8m/ s 2 ).Vistheobjectsvolume( f t 3 or m 3 ). a. Using this formula, write a function named buoyantForce(double ro, double vol, int units) that accepts a fluid density, the volume of an object placed in the fluid, and the units to be used(1=U.S.Customaryunits,2=metricunits), and returns the buoyancy force exerted on the object. b. Include the function written for Exercise 6a in a working C++ program, and use your program to complete the following chart:arrow_forward
- (Misc. application) a. 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_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_forwardPlants Growth Cycle Learning Objectives In this lab, you will practice: Defining a function to match the given specifications Calling the function in your program Using if statements (can combine them with dictionaries) Instructions For every plant, there is a growth cycle. The number of days that it takes starting from being a seed and ending in being a fruit is what is called the growth cycle. Write a function that takes a plant's name as an argument and returns its growth cycle (in days). In your program: Input from the user the name of a plant Check if the input is either "strawberry", "cucumber" or "potato", if Yes: 2.1 Call calculate_growth_cycle 2.2. In function calculate_growth_cycle, check over the plant's name: 2.2.1 If strawberry, print "### The life cycle of a strawberry ###" and return 110 2.2.2 If cucumber, print "### The life cycle of a cucumber ###" and return 76 2.2.3 If potato, print "### The life cycle a potato ###" and return 120 2.3 With the growth cycle…arrow_forward

It should use the following functions: ⚫ void getScore() should ask the user for a test score, store it in a reference param- eter variable, and validate it. This function should be called by main once for each of the five scores to be entered. ⚫ void calcAverage() should calculate and display the average of the four highest scores.
