You have a 500N box and you pull on the box with a rope that is horizontal. The floor is not frictionless. You pull on the box with your rope at a 30 degree angle from the horizontal. You move the box with a constant velocity of 3 m/s. The coefficient of friction is 0.4. a) Draw a free body diagram. b) What is the new tension in the rope (it will not be 200 N).
