Find the Final Velocity of a Body Using Linear Motion Equation in C++

By Anisha Gupta

In this tutorial, we will learn how to calculate the final velocity of a body in C++ using linear motion. We take initial velocity, acceleration and time as parameters.

The formula we are going to use to find the velocity of a body in C++ Using linear motion

Formula used :

 v = u + a*t

where v: final velocity in m/s,

u: initial velocity in m/s,

a: acceleration in m/s^2.

t: time in seconds

This is the Linear motion equation. It is given by Newton.

Step 1: Define variables, make them the float data type. Here, we use four variables: v to define output and u, a and t to define parameters.

Step 2: Take values from the user.

Step 3: Calculate the answer using the formula and print it.

#include <iostream>
using namespace std;

int main() {
    
  float v,u,a,t ;
  cout<<"Enter initial velocity \n" ;
  cin>> u ;
  cout<<"Enter acceleration \n" ;
  cin>> a ;
  cout<<"Enter time \n";
  cin>> t ;
  v = u + a*t ;
  cout<<v ; ;
  
  return 0;
}

If we take u as 1.2, a as 2.2 and t as 3.2. The output will be:

Enter initial velocity 
Enter acceleration 
Enter time 
8.24

Therefore, we calculated the final velocity of a body using Newton’s equation of first law in C++ by this simple code.
