Question 986410: To slide a 317.3 lbf couch across the floor at a constant velocity of 0.7 m/s, you pull on it with a force of 939.3 N at an angle of 32.1o degrees above the floor.
What is the magnitude of the friction exerted by the floor?

The force you pull with exactly counterbalances the friction force since the couch moves at a constant velocity.
So,
F%5Bf%5D=939.3cos%2832%29=796.6N
