Write a program that prompts the user to enter v in meters/second (m/s) and the acceleration a in meters/second squared (m/s²), and displays the minimum runway length.

(Physics: finding runway length) Given an airplane’s acceleration a and take-off 
speed v, you can compute the minimum runway length needed for an airplane to take 
off using the following formula:
length = v²/2a
 Write a program that prompts the user to enter v in meters/second (m/s) and the accel-
eration a in meters/second squared (m/s²), and displays the minimum runway length.
#Beginner
In gcc c++ compiler using namespace std;

#include<iostream>
using namespace std;

int main()
{
float speed,acceleration,length;
cout<<"Enter speed and acceleration :";
cin>>speed>>acceleration;
length=(float)(speed*speed)/(2*acceleration);
cout<<"The minimum runway length for this airplane is :"<<length;
return 0;
}
copy

Output
Enter speed and acceleration :60 3.5
The minimum runway length for this airplane is :514.286

Body Mass Index (BMI) is a measure of health based on height and weight. You can calculate your BMI by taking your weight in kilograms and dividing it by the square of your height in meters

 Body Mass Index (BMI) is a measure of health based on height and weight. You can calculate your BMI by taking your weight in kilograms and dividing it by the square of your height in meters. The interpretation of BMI for people 20 years or older is as follows: BMI Interpretation BMI < 18.5 Underweight 18.5 <= BMI < 25.0 Normal 25.0 <= BMI < 30.0 Overweight 30.0 <= BMI Obese #include<iostream> using namespace std; int main() { //weight in kilograms float kilograms; //height in meters float meters; //enter the values cout<<" enter your weight in kilograms ";cin>>kilograms; cout<<" enter your height in meters ";cin>>meters; //calculate BMI //formula: weight in kilo / (height in meter)*(height in meter) float BMI = kilograms / (meters*meters); cout<<" your BMI is "<<BMI<<endl; if(BMI<18.5) { //BMI < 18.5 Underweight cout<<" you are under ...
