If the man just dropped, then mg = ma and a = g. I see how acceleration will approach g as the mass goes to infinity now. What do you mean redo this? If you do it from the perspective of the block, then mg - T = ma T = mg - ma = 50(10 - 3.33) = 333N

This is 2 problems that continue one another; I solved the first one but do not understand the second. Homework Statement A 100kg man dangles a 50kg 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...
