Question

Newton's 2nd Laws: The absolute acceleration of a particle is proportional to the resultant force acting on it and is in the direction of this resultant force. F = ma a = absolute acceleration Figure 1 Gravitational Law: F F F=G mm2 p2 m m2 G = 6.673x10-"mº/(kges?) Figure 2 As a programmer, you need to write a code to find the newton 2nd Law and Gravitational Law. The details of the code are as follows: 1) For the Newton 2nd Law. Write a code to find the acceleration, a, for rectilinear forces. The equation is as shown in Fig. 1. The input is from the user. The forces need to be initialized into an array. Print the user input to the screen. Calculate the acceleration and print it to the screen. 2) For the Gravitational Law, write a code to find the force, F, as in Fig.2. The code needs to be written by using Class. Declare the class data members and initialize the data members by using a constructor. Print the result to the screen. [Note: for the purpose of the calculation, use this declaration of G, as G= 6.67*pow(10,-11)].

*The solution needs to be in one file

Answer 1

Since there are no languages specified, Let me solve this using c++.

Code:

#include <iostream>
#include<math.h>
using namespace std;


class Gravity{
    public:
    
    float f,g,m1,m2,r;
    
    Gravity()
    {
        g=6.673*pow(10,-11);
        cout<<"\n\n\nEnter the values of m1 and m2 (in KG): ";
        cin>>m1>>m2;
        cout<<"\nEnter the value of r (in m): ";
        cin>>r;
        
        cout<<"\nForce = "<<(g*m1*m2)/(r*r)<<" N ";
    }
};

int main()
{
    int forces[100],mass,n,x,fsum=0;
    
    cout<<"\nEnter number of forces: ";
    cin>>n;
    cout<<"\nEnter the values of forces (in N): ";
    for(int i=0;i<n;i++)
    {
        cin>>forces[i];
        fsum=fsum+forces[i];
    }
    
    cout<<"\nThe forces entered are: ";
    for(int i=0;i<n;i++)
    {
        cout<<forces[i]<<" N, ";
    }
    
    cout<<"\nEnter the value of mass (in KG): ";
    cin>>mass;
    
    cout<<"\nAbsolute acceleration: "<<(float)fsum/mass<<" ms^-2";
    
    
    Gravity obj;
    
    
    
    return 0;
}

Output:

inpu Enter number of forces: 3 Enter the values of forces (in N): 10 15 30 The forces entered are: 10 N, 15 N, 30 N, Enter the value of mass (in KG): 12 Absolute acceleration: 4.58333 ms^-2 Enter the values of ml and m2 (in KG): 23000000 36965000 Enter the value of r (in m): 1000 Force = 0.0567335 N .. Program finished with exit code 0 Press ENTER to exit console.
