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.

Toll roads have different fees based on the time of day and on weekends.
1. Write a function calc_toll() that has three parameters: the current hour of time (int), whether the time is morning (boolean), and whether the day is a weekend (boolean). The function returns the correct toll fee (float), based on the chart below.
Weekday Tolls
Before 7:00 am ($1.15)
7:00 am to 9:59 am ($2.95)
10:00 am to 2:59 pm ($1.90)
3:00 pm to 7:59 pm ($3.95)
Starting 8:00 pm ($1.40)
Weekend Tolls
Before 7:00 am ($1.05)
7:00 am to 7:59 pm ($2.15)
Starting 8:00 pm ($1.10)
Ex: The function calls below, with the given arguments, will return the following toll fees:
calc_toll(8, True, False) returns 2.95calc_toll(1, False, False) returns 1.90calc_toll(3, False, True) returns 2.15calc_toll(5, True, True) returns 1.05

- 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 = 1⁄2 mv2 The variables in the formula are as follows: KE is the kinetic energy in joules, 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.arrow_forward// // Write a function that calculates the amount of money a person would earn over // a period of years if his or her salary is one penny the first day, two pennies // the second day, and continues to double each day.

The function should return the distance, in meters, that the object hasfallen during that time interval. Write a program that demonstrates the function by callingit in a loop that passes the values 1 through 10 as arguments and displays the return value.arrow_forward
- Write a program to gauge the rate of an employee’s raise from the previous year. The program asks for their annual salary in this year and the previous year. It estimates the hike percentage as the difference in their salary from the previous year divided by the previous year’s salary. Your program should allow the user to repeat this calculation as often as the user wishes. Define a function to compute the hike percentage for an employee. The hike rate should be a value of type double giving the rate as a percentage, for example 5.3 for 5.3%.arrow_forwardWrite a function to determine the cost of an automobile insurance premium, based on driver's age and the number of accidents that the driver has had. The basic insurance charge is $500. There is a surcharge of $100 if the driver is under 25 and an additional surcharge for accidents: \# of accidents Accident Surcharge 1 50 2 125 3 225 4 375 5 575 6 or more 700 Then call the function to print the result. example (underline denotes input values): ```Age? 26``` ```Accidents? 3``` ```$725```arrow_forwardWrite a function that asks the user for their birthday month and day and then the function should call a nested function to find out the person’s zodiac sign.

- Q4: the volume of a cylinder is given by the formula: V=r r2L Where r is the cylinder's radius and L is its length. Using the above formula; write a program that uses a function which accepts a cylinder's radius and length as parameters and returns its volume.arrow_forwardIf a year has the digit 7 OR the digit 4 in it, then it is called a “Beautiful year”. For example, 2017, 2014, and 2072 are all beautiful years. If the year has BOTH 4 and 7 in it, then it's an “Amazing year”. For example, the years 2047 and 2074 are amazing years. All other years are “Ugly years”. You need to write a function that takes a year as an argument and return it's type. Then, finally print the returned values in the function call. ================================================ Sample Function Call 1: function_name(2470) Sample Output 1: Amazing year ================================================ Sample Function Call 2: function_name(2170) Sample Output 2: Beautiful year ================================================ Sample Function Call 3: function_name(2021) Sample Output 3: Ugly yeararrow_forward1. A prime number is a number that is only evenly divisible by itself and 1. For example, the number 5 is prime because it can only be evenly divided by 1 and 5. The number 6, however, is not prime because it can be divided evenly by 1, 2, 3, and 6.Write a Boolean function named is_prime which takes an integer as an argument and returns true if the argument is a prime number, or false otherwise. Use the function in a program that prompts the user to enter a number then displays a message indicating whether the number is prime.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.arrow_forward

For example, if an acre of land is valued at $10,000, its assessment value is $6,000. The property tax is then 72¢ for each $100 of the assessment value. The tax for the acre assessed at $6,000 will be $38.40. Write a function that accepts the actual value of a piece of property and displays the assessment value and property tax.
