Rigid rods of negligible mass lying along they axis connect three particles. the system rotates about the x axis with an angular speed of 3.30 rad/s. 4.00 kg = 3.00 m 2.00 kg = -2.00 m 3.00 kg -4.00 m (a) find the moment of inertia about the x axis kg m² (b) find the total rotational kinetic energy evaluated from 192. (c) find the tangential speed of each particle. 4.00 kg particle 2.00 kg particle m/s 3.00 kg particle m/s (b) find the total rotational kinetic energy evaluated from (c) find the tangential speed of each particle. 4.00 kg particle m/s 2.00 kg particle m/s 3.00 kg particle m/s (d) find the total kinetic energy evaluated from mv 2. (e) compare the answers for kinetic energy in parts (b) and (d).
