Atrain moving west with an initial velocity of 20 m/s accelerates at 4 m/s2 for 10 seconds. during this time, the train moves a distance of how many meters.

By definition, the distance traveled is given by:

Where,

a: acceleration

vo: initial speed

t: time

Substituting values we have:

Therefore, the distance covered was 400 meters.

During this time, the train moves to a distance of 400 meters

potential energy is directly proportional to height.

more height = more potential energy.

greatest increase in height = greatest increase in potential energy

where are the points with the greatest increase in height ?

has to be c-e or d-e .

it is very well related to a lot of things but with my limited knowledge i can confidently say that the answer is space.
