Explanation:

In odyssey-ware this is your answer.

hèllo, sorry i really need some more points so if you need this qustion answered than retype it

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.
