A 65 kg person wants to get to the top of a 2m high ledge by swinging up to the top by running and grabbing a suspended rope suspended 5m above the ground by a tree. The acceleration due to gravity is 9.8 m/s2. How fast should the person run in older to just make it to the top? At that speed, what is the initial tension in the rope as the person just leaves the ground (i.e, assume the rope is still vertical, but the person is not touching the ground)?
