An Atwood machine consists of two masses, ma = 7.0 kg and mg= 9.0 kg, which are connected by a rope that hangs over a pulley. The pulley is a uniform cylinder (I= ½ MR2) of radius R=0.25m and mass M=1.0 kg. Initially ma is at rest on the ground and mg is 2.5m above the ground. Determine: A. The linear acceleration of blocks mĄ and mg. B. The velocity of mg when it hits the ground. (Assume an acceleration of 2 m/s? if you didn't solve part A). C. The angular momentum of the pulley when mg hits the ground. (Assume a final velocity of 4 m/s if you didn't solve part B). (Hint: The tensions on the blocks are NOT equal).

Harry sets some clay (m = 3.25 kg) on the edge of a pottery wheel (r = 0.600 m), which is initially motionless. He then begins to rotate the wheel with a uniform acceleration, reaching a final angular speed of 2.400 rev/s in 3.00 s, while not touching the clay. As a result, the clay is subject to a tangential and centripetal acceleration while it sits on the edge of the wheel. a. What force is responsible for the tangential acceleration, and what force is responsible for the centripetal acceleration? b. Which of these two forces, tangential or centripetal, will necessarily fail to keep the clay in place on the wheel first? Why?

Problems 62 and 63 are paired. 62. C A disk is rotating around a fixed axis that passes through its center and is perpendicular to the face of the disk.
