Question

Tens Assume a tennis ball weighing 58.5 grams is bouncing strong initially and then weakens slowly by an amount eA-2 of ballyweight each time it bounces. Write a C++ program to calculate how many times the ball will bounce if it is dropped from a height before it is flattened to ground (i.e. 0.0 cm height).

Answer 1

Hopefully all yours doubt will clear if you have left with any doubt please let me know in comment. I will try my best to resolve that.

Here I am posting code and screenshot of output.

Code :-

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

int main()
{
// variable declaration
double height, weight = 58.5;
// initializing counter with zero
int count = 0;
// enter initial height
cout<<"Enter initial height of ball : "<<endl;
cin>>height;
// flatten to ground means in general is when height is less then 0.000001 cm you can change it according to your need.
while (height >= 0.000001)
{
// increment in count i.e. bounce
count++;
// new height after bounce ( weakens e^(-2) of height )
height *= exp(-2);
}
// print result
cout<<"ball will bounce " <<count<<" times before flatten to ground"<<endl;
}

Screenshot of output :-

O "C:\Users\Rajkumar Pilania Documents\ball.exe", Enter initial height of ball : 20 ball will bounce 9 times before flatten to ground Process returned @ (exe) execution time : 2.370 s Press any key to continue.
