Question 13 X 40 cm axis 20 cm 60 cm A system of point particles rotates at 5 revis as shown in the figure. Each particle has a mass of 250 grams and they all lie in the same plane. What is the moment of inertia of the system about the axis of rotation? Question 14 In a linear momentum simulation you tried to predict the final velocities of two masses (m, and my) given that m, - 2.5 kg and ma - 0.5 kg. Mass 2 was " initially at rest while mass I trave's directly to it with a velocity 2m/s. What is the final velocity of mass 2. If the two masses undergo perfectly elastic collision? Just input any number in the answer box
