1. The problem statement, all variables and given/known data In the figure the man hanging upside down is holding a partner who weighs 570 N. Assume that the partner moves on a circle that has a radius of 6.50 m. At a swinging speed of 4.25 m/s, what force must the man apply to his partner in the straight-down position? 2. Relevant equations Fc=(mv^2)/(t) 3. The attempt at a solution (570*(4.25)^2) / 6.5 1580 n? If my logic is wrong, please tell me.
