If yellowstone supervolcano erupts while you are visiting, and the ash cloud accelerates at 20 meters per second squared, how fast is it moving one minute ater the eruptiond

1200m/s

Explanation:

Given parameters:

Acceleration = 20m/s²

Time taken = 1 minute = 60 seconds

Unknown:

Speed = ?

Solution:

The acceleration of a body is its rate of change of velocity with time. It is mathematically expressed as:

         Acceleration =

  Change in velocity = acceleration x time

Now, velocity and speed are very similar and are often interchanged. It is excellent to bear in mind that velocity is form of speed that takes cognizance of direction.

  Change in velocity = 20 x 60 = 1200m/s

Therefore, the ash is moving at a rate of 1200m/s

what type of charge does it have? negative

f=ma newton's second law 7x8=56n
