1. The problem statement, all variables and given/known data A man weighing 980 N slides down a rope that can support a weight of only 755 N. a) How is this possible? b) What is the least acceleration he can have without breaking the rope? c) What will his minimum speed be after sliding down 8.0 m? 2. Relevant equations Not specified, but I think it's ΣF = ma, and W = mg. 3. The attempt at a solution For a) I detail here that because of the speed at which the person is moving, he weighs less than he would if he were stationary, is this correct? For b) For this, I used "W = mg". I figured that the gravity is known and so is his weight, so I transposed this and found his mass to be 100 kg. (980/9.8). So now that I had the mass of the person, I put into the equation "W = mg", that the weight must = 755 and the mass = 100 kg and I got that -7.55 m/s2 was the speed, is this correct? For c) I wasn't sure how to solve this question, could someone help me out? Thank you.
