A round tube weighs 30kg. If the tube is stood on end, it pushes down on the floor with a pressure of 20N/m2. How many square inches is the end of the tube? I will mark the brainliest for the answer with a solution… ​

acceleration = (change in speed) / (time for the change)

change in speed = (20-120)= -100 m/s.

1.5 min = 90 sec

acceleration = -100/90 = -1.11 m/s^2.

we don't care about the 150kg or the 2,500 meters. they don't make any difference.
