A old massless rope of 12 meters attached to a ceiling can sustain a maximum tension force of 1200N before breaking. An 85 kg person climbs up the rope. What is the minimum possible time in which he can climb to the top without breaking the rope?
My issue is figuring out the forces involved as the person climbs up the rope.
would there be an applied force downward, because the person must push down to climb up the rope? Or is that not counted because the person always weighs the same? So would it be:
Fgravity + FApplied = Fmax tension?
