A person of mass 50.0 kg is at the bottom of a cave. The cave has a depth of 32.5 meters and the person is to be pulled out of the cave vertically by a rope, starting from rest. What is the shortest amount of time that this could take if the rope can withstand a maximum tension of 550.0 N without breaking?
I think this is how you tackle this problem:
Solve for a:
You know acceleration, so solve for time (t) using the following kinematic equation:
Solve for t:
