WebA free-falling object has an acceleration of 9.8 m/s/s, downward (on Earth). This numerical value for the acceleration of a free-falling object is such an important value that it is given a special name. It is known as the acceleration of gravity - the acceleration for any object moving under the sole influence of gravity. Web1 apr. 2000 · If you fire a gun into the air, the bullet will travel up to a mile high (depending on the angle of the shot and the power of the gun). Once it reaches its apogee, the bullet will fall. Air resistance limits its speed, but bullets are designed to be fairly aerodynamic, so the speed is still quite lethal if the bullet happens to hit someone. WebWe find that it takes 249,5 seconds to fall into space! During these few minutes you would experience a gradual decrease in temperature, followed by a rise in temperature followed by a sudden drop in temperature again. In the meantime you would also quickly get some serious trouble breathing. danmar b100 wheel balancer youtube
