Two boys push on a box. One pushes with a force of 125 n to the east. The other exerts a force of 165 N to the north. What is the size and direction of resultant 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.

the answer is a. hope this .

inverse v=i*r
