- You're watching Disney on ice through a streaming service. Ariel and Aurora 1.4 m/s (each with mass equal to 55 kg), glide in the directions shown (parallel to each other). Their velocities are opposite direction, but both equal to 1.4 m/s. Aurora carries one end of a long massless rod. Their paths are separated by 3.0 m. The other skater grabs the end of the pole as she reaches it. They both then rotate around the center of the rod. For the problems below, assume that there is no friction between the princesses and the ice and we're talking about after the two princesses both hold the rod. 1.4 m/s 1. What is the translational (linear) speed of the two-princess system, specifically, at what speed is the center-of-mass (since everything is symmetric, the c.o.m, is at the center) moving? 2.
