1. Two ice skaters, each with mass M = 72.5 kg, both moving with speed V = 9 m/s, approach each other along straight-line parallel paths that are separated by a distance of D = 3.6 m. When directly opposite each other, the skaters grab the ends of a light rod that is the same length as the distance between them. What is the initial speed of rotation of the joined skaters in rad/s?
2. Equations
maybe use conservation of momentum to find vfinal
m1vo+m2Vo=m1vf+m2vf
then use ac=v^2/r
r comes from d/2
3. this results in the incorrect answer. I'm unsure of how to solve this problem. Am I using the wrong equations?
