Answer:
13.9 m/s
Explanation:
The velocity of the train along the inclined surface is given by the ratio between the distance travelled, d, and the time taken, t:
where we have
d = 400 m
t = 5 s
Substituting,
This is the velocity of the train along the inclined plane. Now we can find the vertical component of the velocity by using the formula:
where 
is the angle of the slope. Substituting, we find
The heat and energy of coal burning is more easier and more efficient to turn into electricity than any method using renewable resources.
The answer is Elliptical orbit.
Hope this helps!
I don’t use the metric system, so I used feet and then went back.
25 meters is about 82 feet.
So around 82 feet per minute (kinda slow LOL)
82 (feet per minute) x 90 (minutes) = 7380 feet (in 90 minutes)
7380 feet is equal to 2249.424 meters.
(I hope that helped)
