Explanation:
If you want to get speed, u have to divided distance over time
The lowest speed will lose
Since its a sphere, the top is seen first because its the tallest part if the ship. If the earth was flat, the whole ship would be seen.
|Acceleration| = (change in speed) / (time for the change).
Change in speed = (6 mi/hr - 25 mi/hr) = -19 mi/hr
Time for the change = 10 sec
|Acceleration| = (-19 mi/hr) / (10 sec) = -1.9 mile per hour per second
Admittedly, that's a rather weird unit.
Other units, perhaps more comfortable ones, are:
-6,840 mi/hr²
-2.79 feet/sec²
It depends on the brightness of its light—which is really just the sun's light reflecting off of the moon's<span> surface—and the earth's rotation. In order for the </span>moon<span> to be visible in the sky, it needs to be above the horizon. </span>
