Homework Help: Physics

Posted by Aaron on Sunday, March 1, 2009 at 2:49pm.

A daredevil attempts to swing from the roof of a 24m high bulding to the bottom of an identical building using a 24m rope. He starts from rest with the rope horizontal, but the rope will break if the tension force in it is twice the weight of the daredevil. How high is the rope above level when it breaks? (Hint: Apply the law of conservarion of energy) Also, the building are 24m apart.

I don't understand; how can I do this without knowing the daredevil's weight?
