Hello all!
I recently got an assignment from my pressor that ask me to Write a program that computes the duration of a projectile’s flight and its height above the ground when it reaches the target.
He gave us the following equations to work with:
a. time = distance/ velocity x cos(0)
b. height = velocity x sin(0) x time - (g x time^2)/2
distance, velocity, and angle are all inputs from the user and g is a gravitational consistency of 32.17

Purpose:
Write a program that computes the duration of a projectile’s flight and its height above the ground when it reaches the target.
Analysis/ Data:
1. inputs: angle, distance, velocity (float)
2. output: time in seconds, height (float)
3. equations
a. time = distance/ velocity x cos(0)
b. height = velocity x sin(0) x time - (g x time^2)/2

#include <iostream>
#include <cmath>
using namespace std;
float velocity, target_distance, angle;
float grav_const = 32.17;
float inPuts( ) {
cout << "please enter the velocity of the projectile: ";
cin >> velocity;
cout << "it's distance: ";
cin >> target_distance;
cout << "The angle: ";
cin >> angle;
return velocity, target_distance, angle;
}
float time ( ) {
inPuts( );
return target_distance/ velocity * cos(angle);//equation for time
}
float height() {
inPuts();
time();
float height1 = velocity * sin(angle) * time() - (grav_const * (time() * time())) / 2;//equation for height
return height1;
}
int main() {
cout << time() << endl << height();
}
I'm using a different ide so I'm not sure if I copied and pasted correctly.
I keep getting consistent numbers when I input numbers yet they are wrong (ex: 1, 1, 1 for the inputs ->.54 for output or time). Also, the code consistently repeats 5 times yet I have no loops. I was tight for time so I only tested to see if the computer ran through each function.
