Acceleration of gravity.

Compute the acceleration of gravity for a given distance from the earth’s center, distCenter, assigning the result to accelGravity. The expression for the acceleration of gravity is: (G * M) / (d2), where G is the gravitational constant 6.673 x 10-11, M is the mass of the earth 5.98 x 1024 (in kg) and d is the distance in meters from the earth’s center (stored in variable distCenter)

#include <stdio.h>

int main(void) {
 double G = 6.673e-11;
 double M = 5.98e24;
 double accelGravity;
 double distCenter;

distCenter = 6.38e6;

accelGravity = (G * M) / (distCenter * distCenter);

printf("accelGravity: %lf\n", accelGravity);

return 0;
