Asked Feb 13, 2020
A stuntman with a mass of 85.0 kg swings across a pool of water from a rope that is 10.0 m. At the bottom of the swing the stuntman's speed is 8 m/s. The rope's breaking strength is 1,000 N.
(a) Will the stuntman make it across the pool without falling in?
(b) What is the maximum speed (in m/s) that the stuntman can have at the bottom of the swing on this vine to safely swing across the river?
