Got it. Thanks a lot chrisk! So in that case, the net force is 30N (the horizontal push). The acceleration is f=ma -> 30=75a -> a=.4 And the velocity that the couch will reach is .4 x 5 = 2 Correct?

Not simple for me. I'm only on my second week of basic high school physics and I've missed most of my course due to being sick. So bear with me if I don't understand. :blushing: Why would the normal forces cancel out? How do you know that gravity the same as the support force?

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...
