A man is to be released from rest on a swing pulled away from the vertical by an angle of 22.1 degree. The two frayed ropes of the swing are 2.75 meter long, and will break if the tension in either of them exceeds 320 Newton.
(a) Find the maximum weight the man can have and not break the ropes?
(b) If the person is released at an angle greater than 22.1 degree, does the maximum weight increase, decrease, or stay the same?
