Sphere A has a horizontal speed of 40. meters per second and sphere B has a horizontal speed of 20. meters per second. Which statement best describes the time required for the spheres to reach the ground and the horizontal distance they travel? If it was thrown horizontally or dropped, and hit the ground 3.03 seconds later, then it hit the ground moving at a speed of 29.694 meters (97.42-ft) per second. Meters are divided by seconds, so the answer is 6 m/s (metres per second). You can find the average speed of an object if you know the distance travelled and the time it took. For example, to find the time taken to make a journey, we need the length of the journey and the speed of travel.It is widely known that in the past food was somehow more better than it is today.
