Aforce of 5.25 newtons acts on an object of unknown mass at a distance of 6.9..*.108 meters from the center of earth. to increase the force to 2.5 times its original value, how far should the object be from the center of earth?

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.
