Without friction, Newton's second law, in the form F=ma would apply.100=50a. So the acceleration should be 2m/s^2100-friction = 50x1.5100-friction = 75100-75=friction25N = friction
You can tell if vector is an unit because it has something to do with taking the magnitude of the vector.
also has a length 1. thus you should use pythagoras to check.
Hope this help
