1. The problem statement, all variables and given/known data A 100 kg man dangles a 50 kg mass from the end of a rope. If he stands on a frictionless surface and hangs the mass over a cliff with a pulley, the tension in the rope will be: (A) 250 N (B) 333 N (C) 500 N (D) 667 N The answer is B but I am having a difficult time setting this one up. 2. Relevant equations F=ma 3. The attempt at a solution Okay, so we know that for the man, T = ma because he is on a frictionless surface and the block is mg = T+ma. Some others have posted this problem on this site but I need clarification for the second equation listed above. I cannot combine these equations because the masses are different. So, what I did was alter the equations as man: T=2ma block: mg = T+ma substituting gives me: mg = 2ma +ma therefore, g = 3a and a = 3.33 m/s But when I go back to my "altered" equations to solve for T, I get 667 N which is wrong. Anyone know what I am doing wrong here?
