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=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.

A bank charges $10 per month, plus the following check fees for a commercial checking account:
$0.10 each for less than 20 checks
$0.08 each for 20 through 39 checks
$0.06 each for 40 through 59 checks
$0.04 each for 60 or more checks
Write a function BankCharges() that allows the user to enter the number of checks written and computes and displays the bank’s service fees for the month. All checks for the month are assigned the same charge, based on the total number of checks written during the month. Use the following test data to determine whether the application is calculating properly. In each case, the customer is charged only a single rate, based on the total number of checks. Your solution should clearly show the function.

- (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(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_forwardMark the following statements as true or false: a. To use a predefined function in a program, you need to know only the name of the function and how to use it. (1) b. A value-returning function returns only one value. (2, 3) c. Parameters allow you to use different values each time the function is called. (2, 7, 9) d. When a return statement executes in a user-defined function, the function immediately exits. (3, 4) e. A value-returning function returns only integer values. (4) f. A variable name cannot be passed to a value parameter. (3, 6) g. If a C++ function does not use parameters, parentheses around the empty parameter list are still required. (2, 3, 6) h. In C + + , the names of the corresponding formal and actual parameters must be the same. (3, 4, 6) i. A function that changes the value of a reference parameter also changes the value of the actual parameter. (7) j. Whenever the value of a reference parameter changes, the value of the actual parameter changes. (7) k. In C++, function definitions can be nested; that is, the definition of one function can be enclosed in the body of another function. (9) l. Using global variables in a program is a better programming style than using local variables, because extra variables can be avoided. (10) m. In a program, global constants are as dangerous as global variables. (10) n. The memory for a static variable remains allocated between function calls. (11)arrow_forward

If this quantity is positive, the function calculates A. If the quantity is negative, a, b, and c do not form a triangle, and the function should set A=1. The value of A should be returned by the function.arrow_forward(Statics) A beam’s second moment of inertia, also known as its area moment of inertia, is used to determine its resistance to bending and deflection.

Using this formula, write a function called beamMoment() that accepts two double- precision numbers as parameters (one for the base and one for the height), calculates the corresponding second moment of inertia, and displays the result. b. Include the function written in Exercise 4a in a working program. Make sure your function is called from main().
