(a) If the moment of inertia of the sprocket is 4.32 kgm2, what is the rotational kinetic energy of the sprocket? (b) What is the centripetal acceleration of the chain as it makes contact with the sprocket? (c) Given that the torque on the sprocket is 3.24 Nm what is the angular acceleration of the sprocket?

You're feeling particularly lazy and decide to open a door by firing a bullet at it. The door has a mass of 10.7 kg and is 1.25 m wide, and the 10 g bullet, traveling at 420. m/s, hits the door at the edge opposite the hinges. The bullet stops inside the door, which then swings open. What is the angular velocity of the door just after the bullet hits it?
A 750 g disk and a 760 g ring, both 15 cm in diameter, are rolling along a horizontal surface at 1.3 m/s when they encounter a 13 ∘ slope. How far up the slope does the disk travel before rolling back down? How far up the slope does the ring travel before rolling back down?
This problem describes one experimental method for determining the moment of inertia of an irregularly shaped object such as the payload for a satellite. Figure P10.47 shows a counterweight of mass m suspended by a cord wound around a spool of radius r, forming part of a turntable supporting the object. The turntable can rotate without friction. When the counterweight is released from rest, it descends through a distance h, acquiring a speed v. Show that the moment of inertia I of the rotating apparatus (including the turntable) is mr2((2gh)/v2) – 1)
Still think that unit conversion isn't important? Here is a widely publicized, true story about how failing to convert units resulted in a huge loss. In 1998, the Mars Climate Orbiter probe crashed into the surface of Mars, instead of entering orbit. The resulting inguiry revealed that NASA navigators had been making minor course corrections in SI units, whereas the software written by the probe's makers implicitly used British units. In the United States, most scientists use Sl units, whereas most engineers use the British, or Imperial, system of units. (Interestingly, British units are not used in Britain.) For these two groups to be able to communicate to one another, unit conversions are necessary. The unit of force in the SI system is the newton (N), which is defined in terms of basic Sl units as 1 N=1 kg · m/s?. The unit of force in the British system is the pound (lb), which is defined in terms of the slug (British unit of mass), foot (ft), and second (s) as 1 lb =1 slug ·…
