Q. A stone is dropped at t = 0. A second stone, with 2 times the mass of the first, is dropped from the same point at t = 190 ms. (a) How far below the release point is the center of mass of the two stones at t = 390 ms? (Neither stone has yet reached the ground.) (b) How fast is the center of mass of the two-stone system moving at that time?

Q. A floppy disk for a personal computer rotates with a constant angular speed of 31.4 rad/s about an axis perpendicular to the disk at its center. (a) Find the tangential speed of a point that is 0.0410 m from the center of the disk. (b) What is the magnitude of the centripetal acceleration at this point?
