Question
2) A 500 g box is being pulled by a rope across a level surface. The rope is horizontal.
The tension in the rope is 10 N to the right, and there is a 7 N kinetic friction force
acting on the box.
a.
b.
Draw a free body diagram for the box.
What is the net force acting on the box in the x-direction?
C. What is the net force acting on the box in the y-direction?
d. What is the acceleration of the box? (magnitude and direction)
e.
One of the forces on your free body diagram should be the normal force
(make sure it is there!). For the normal force, what is the object, and what is
the agent?
f.
Is there a Newton's third law force pair associated with the normal force
acting on the box?
g. If your answer to f was yes, describe the equal and opposite force by
answering these questions: What is the object, what is the agent, and what
kind of force is it?
