Tension and Time

  1. Oct 30, 2013 #1
    Illinois Jones is being pulled from a snake pit with a rope that breaks if the tension in it exceeds 725 N. If Illinois Jones has a mass of 62 kg and the snake pit is 3.9 m deep, what is the minimum time necessary to pull our intrepid explorer from the pit?



    F=ma and a=d/t^2



    I put in 725 for the force so I had 725=(62kg)(a) and that gave me 11.69 for a, but that doesn't really make sense. That may be right but seems like an insanely high acceleration. Was I wrong in doing that?

    The acceleration is produced by the net force. The tension in the rope is not the only force acting on him.
