Aperson wax walk at 1m/sand then accelerate at 2 m/s^2 for 2 seconds
after theses two seconds the person is moving at m/s and has traveled

The person is moving at 5 meters per second (m/s)

The person has traveled 6 meters

Explanation:

This is an example of accelerated motion (motion under acceleration), and therefore we need to use the appropriate equations of motion for it.

The information we have includes:

1) The initial velocity () of the person = 1 m/s

2) The person's acceleration () = 2

3) The time (t) the person moves under accelerated motion = 2 seconds

The following two equations are those to find the final velocity under accelerated motion, and the distance covered (from initial position to final position ) under accelerated motion:

We use the first equation and the information given, to find the speed of the person after 2 second under this motion:

We use the second formula to find the distance traveled by the person:

as we know our atmosphere or air have different levels. every level has other gasses, and every gas has another permeability. when the light comes from lower permeability to higher permeability, it changes its direction. so that means that when the light comes from the moon to the earth, it changes it's direction many more times. it basically means that the shape of the light part of the moon is changed on the earth.
