A 111 kg111 kg horizontal platform is a uniform disk of radius 1.97 m1.97 m and can rotate about the vertical axis through its center. A 68.7 kg68.7 kg person stands on the platform at a distance of 1.11 m1.11 m from the center, and a 25.3 kg25.3 kg dog sits on the platform near the person 1.41 m1.41 m from the center. Find the moment of inertia of this system, consisting of the platform and its population, with respect to the axis.

Aboxcar traveling at 12 m/s approaches a string of 5 identical boxcars sitting stationary on the track. the moving boxcar collides and links with the stationary cars and they all move off together along the track. what is the final speed of the cars immediately after the collision? (you may take the mass of each boxcar to be 18,537 kg.)
