Mike is pushing a box with a force of 10 N to the left. Bill is pushing on the same box with a force
of 8 N to the right. What is the net force on the
box?

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.

i don't know that i agree with that but what's the question ?

lol

explanation:

c) up is the direction the magnetic force is acting on the charge.
