You need to write a C++ program that has

When an object falls
because of gravity, the following formula can be used to determine the distance
the object falls in a specific time period:

` d = 1/2 gt^2`                                                                   

Where d is the distance in
meters, g is 9.8(constant of gravity) and t is the amount of time, in seconds, that the
object has taken to fall.

You need to write a C++ program that
has:

1.      A
function fallingDistance which:

v  Accepts
an object’s falling time (in seconds) as an argument.

v  Calculates
the distance, in meters, that the object has fallen in that time.

v  Returns
this calculated distance.

2.      In
the main() function there is a:

Ø  A
loop struct in which:

v  the
function fallingDistance is called passing data given in the table.

v  Sum
of all these distances is calculated.

Ø  Average
distance is calculated and displayed.

3.      Following
is the time data:

Time(seconds)

1

3

5

7

9

 

4.      You
can use any of the loop structs like…for-loop, while or do-while loop.

5.      The
formula to calculate average is:

              Average = (sum of values) / number of values

 Sample screenshot of the program is given below:

 Solution:

#include <iostream>

double fallingDistance(double time) {

    const double g = 9.8;

    double distance = 0.5 * g * time * time;

    return distance;

}

int main() {

    double times[] = {1, 3, 5, 7, 9};

    int numTimes = sizeof(times) / sizeof(times[0]);

    double sum = 0;

    for (int i = 0; i < numTimes; i++) {

        double distance = fallingDistance(times[i]);

        sum += distance;

    }

    double average = sum / numTimes;

    /*std::cout << "Sum of distances covered = " << sum << "m\n";*/

    std::cout << "Average distance covered = " << average << "m";

    return 0;

}
