A. Large and pulls objects towards itself
Let d = distance that the fugitive travels to get on the train.
Let t = the time to travel the distance d.
The fugitive starts from rest accelerates at a = 3.8 m/s².
Therefore
(1/2)*(3.8 m/s²)*(t s)² = (d m)
1.9 t² = d (1)
The train travels at constant speed 5.0 m/s.
Therefore
(5.0 m/s)*(t s) = d
5t = d (2)
If the fugitive successfully boards the train, then equate (1) and (2).
1.9t² = 5t
t = 0 or t = 2.6316 s
Ignore t = 0, so t = 2.6316 s.
The speed of the fugitive after 2.6316 s, is
v = (3.8 m/s²)*(2.6316 s) = 10 s
This speed exceeds the maximum speed of the fugitive, therefore the fugitive fails to get on the train.
Answer: The fugitive fails to get on the train.
I think it’s when the sun explodes because since we need to the sun I think the human population will fall out. also a huge war, a meteoroid huge as the one that killed the dinosaurs comes down, there is so much ways on how the human population can stop growing. hope this help at least!
Answer:
C.
Explanation:
The velocity is going down at the beginning of Carla's trip, so acceleration is decreasing; this means she was slowing down. Then, the line hits 0, which means she isn't moving. Then, she started moving again after 4 seconds, so she was speeding up.
Yeah, because of it's short frequencies, ultraviolet rays can travel through empty space- D
