The missing coordinate r is -2
Answer:
1090
Step-by-step 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.
