Two cylinders of identical mass but with different radii roll down a ramp. in your initial post to the discussion, respond to the following: which cylinder gets to the bottom first? which cylinder has more total kinetic energy? why? now, using the concept of moment of inertia, explain why two objects rolling down an incline (even if they have identical masses) roll at different speeds. finally, be sure to respond to at least two of your peers’ posts.
