1. Probem Suppose a couch with a mass of 75 kg was resting on a frictionless floor. Roy wants to move the couch to the other side of the room so he pushes it with a force of 30 N for 5.0 seconds. a) Make a free body diagram of the couch. b) Find the net force on the couch. c) Find the couch's acceleration. d) What velocity will the couch reach? 2. Relevant equations Acceleration=force/mass 3. The attempt at a solution a) Will this be applied force of 30N pointing right, normal force pointing up, and force of gravity down? In that case, what are the values for the normal and gravity force? b) Depending on above. Once I know the values I will add them/subtract to find the net force.
