Homework Statement
a man swings from a rope which is 10 feet long. his mass is 80 kg and at the bottom of his swing, he is going 8 m/s. The max tension the rope can take without breaking is 2000 N. Does he make it?
Homework Equations
Fc = mv^2/r
The Attempt at a Solution
first i had to convert the feet to meters (3.05m). then i think the way to solve it is to first figure out the centripetal force generated by swinging - this would be (80 kg)(8)^2/(3.05 m) = 1678 N.
does this mean he's ok because the tension in the string doesn't exceed the 2000 N limit or do I need to include his weight in the problem?
