Any object that is launched as a projectile will lose speed and, as a result, altitude, as it travels through the air. The rate at which the object loses speed and altitude depends on the amount of force that way applied to it when it was launched. It is also dependent on the size and shape of the item. This is why something like, say, a football is much faster to fall to the ground than a bullet.
The answer is 8 meters per second 8m/s because 200 divided by 25 is 8
This isn’t anything related to physics dude
Time = distance / speed
Time = (4,800 meters) / (3 x 10⁸ m/s)
<em>Time = 0.000016 second</em>
This number is not one of the choices on the list. My hunch is that you copied the distance wrong.
If the estimated distance to the star is actually 4.8 x 10¹⁵ km, instead of 4.8 km, then the answer would be close to 500 years <em>(B)</em>.
There's no way a star can be "4.8 km away from the Earth". You can <em>walk</em> that far in about an hour, and passenger jet airplanes fly <em>twice</em> as far as that away from the Earth !
