Question

Write a program that allows the user to enter a time in seconds and then outputs how far an object would drop if it is in freefall for that length of time. Assume no friction or resistance from air and a constant acceleration of 32 feet per second due to gravity. Use the equation

Distance = * acceleration * time2

Answer 

#include<iostream>
using namespace std;

#define ACCELERATION 32

int main() 
{
  //Variables
  int time;
  double distance;

  //Input from the user
  cout<<" Enter time(Seconds):";
  cin>>time;

  //Compute distance using the formula:
  //distance=(acceleration*time^2)/2
  distance = ((ACCELERATION * time *time)/2);

  //Display result
  cout<<"Traveled distance:" << distance <<"\n";
}

Result output:

Enter time(Seconds):60
Traveled distance  :57600
