4. Suppose this 3-robot system can be approximated with their masses equally spaced away from each other, as in an equilateral triangle (see Fig. 1). Figure 1: Spinning Robots (a) (15pts) What is the moment of inertia of the system when the axis is perpendicular to the most massive of all the robots and their spacing is 1.20 m? (Perpendicular here means an axis going from the floor to the roof, through the robot.) (b) (10pts) How many times do these robots revolve around their center-of-mass if they slide for 5.20 s and their angular velocity is 3.00 rad/s? Despite the robots having actuators and indestructible bodies on their side, they are surprisingly inept when it comes to hockey. Maybe they should stick to robot fighting or apocalypses.
