If a vial contains 400 MBq of fluorine-18 (F-18) at 12:00 on 20 March 2019, how much radioactivity will be present in the vial at 14:00 on 20 March 2019? Please input your answer

in Bq and Ci.

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.
