The arrow pointing up is 25N, the arrow pointing down is 25 N and the other arrows look like the picture. 15 N<---[#]----> 20 N

The force diagram for a 2 kg box being pushed along the floor to the right at 20 N is shown below. Find the missing variables. You are to find the Force net and acceleration.

Incorrect answer:
5 N left

You subtracted in the wrong direction. Horizontal net force = rightward 20 N − leftward 15 N = 5 N to the right. Vertical forces (25 N up and 25 N down) cancel, so no vertical net force.

Use Newton’s 2nd law: a = Fnet/m = 5 N / 2 kg = 2.5 m/s² to the right.

Answers: Fnet = 5 N right; a = 2.5 m/s² right.
