Atrain traveling at 18.2 m/s accelerates to 39.9 m/s over a distance of 1250 m. how long did it take the train to cover this distance?

43.4 s

Explanation:

First of all, we can find the acceleration of the train by using the equation:

where

v = 39.9 m/s is the final speed

u = 18.2 m/s is the initial speed

a is the acceleration

d = 1250 m is the distance covered

Solving for a,

And now we can fidn the time taken, by using the formula:

i dont think you are wrong for wanting to get even with someone who did you wrong.

(i'm an eye for an eye kind of person) but if this person hurt you in a sexual way, i dont suggest doing anything to him. he should be taken to the proper authorities, you could go to jail depending on what you do. if it was something small like your sibling took your spot on the couch, than yea, i would get even with him by taking one of his favorite snacks lol. but i dont suggest you doing anything illegal.
