Alfonso is trying to move a new sofa into his apartment. Unfortunately, he forgot to measure the size of his doors and it turns out the sofa won´t fit through! He must therefore lift the sofa from the street and bring it into the apartment through his window. The sofa has a mass of 160Kg. With a rope Alfonso can pull upwards with a force of 400N. Calculate how much mass Alfonso can lift alone. State whether he will need to ask for help from his friends, and if so, how many friends will he need to ask?

i got a hair cut today from my mom not to flex just to flex kim jon un is one rad fellow i'd say you'd need to take the hairline in kinda like a box shape like someone rammed a lego brick into your head. from there you really need to take the top up keeping with that boxy aesthetic, finally coat the whole thing with gel if your country economics are failing or whatever you can just coat it with the starving children's food rations. about 5 orphans per strand is a good ratio. good luck with the fresh cut my dude
