Uniform circular motion?

Question

on an ice rink, two skaters of equal mass grab hands and spin in a mutual cicle once every 2.5 seconds. If we assume their arms are each .80m long and their individual masses are 60kg, how hard are they pullin on one another?

Answer 1

F = mv^2/r = mrω^2 = 60*0.8(2π/2.5)^2 = 303.1942 N
