P15: Two metal bars are welded together at right angles. Each has a mass of 1.5 kg, and is 50 cm long. The object is free to pivot around its center of mass, and a force of 0.25 N is applied at angle of 350 as shown in the gure. Please answer each of the folowing questions. a) What is the torque due to the force F? b) What is moment of inertia of the combined bars? 0) Assuming that the system starts at rest, what is the angular velocity of the bars after 3 seconds? 50 cm
