Q1. A massless rod of length 1m has a 2.00 kg mass attached to one end and a 3 kg mass attached to the other. The system rotates about a fixed axis perpendicular to the rod that passes through the rod 30.0 cm from the end with the 3kg mass attached. The kinetic energy of the system is 100 J. What is the angular speed of the system?
