Question

A 40.0 kg box is being pushed across the floor to the right with 200 N of applied force. There is 120 N of frictional force opposing the motion.

What is the net force acting on the box?

What is the acceleration of the box?

Answer 1

The net force is 80N to the right
The acceleration is 80/40 = 2 m/s^2 to the right
