A child is trying to push her bed to the left with a force of 90 N, at the same time the friction exerted by the surface is 20 N. Her bed weighs 150 N and the floor holds it with a normal force of the same magnitude. Her brother comes along but instead of helping he pushes the bed, trying to stop her from moving it. He is not very helpful, and he is pushing to the right with a force of 70N. What is happening to the bed?
It is moving to the right with 0N
It is moving to the right with 10N
It is not moving
It is moving to the left with 0N
It is moving to the left with 10N
