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