Illustrate the nuclear fission and fusion reaction of 92U 235 and formation of 2He4 by the fusion of two protons.​

it about 600 mph from what i calculated

what question you dont ask a question

explanation:

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.
