Determine radial velocity of ring as it reaches moving end : A ring is fitted loosely (with no friction) around a long, smooth rod of length L = 0.561 m. The rod is fixed at one end, and the other end is spun in a horizontal circle at a constant angular velocity of ? = 3.57 rad/s. The ring has zero radial velo.. |

What is the work done by the force of gravity : A 255 kg piano slides 4.2 m down a 30° incline and is kept from accelerating by a man who is pushing back on it parallel to the incline (Fig. 6-36). The effective coefficient of kinetic friction is 0.40 Figure 6-36 |

What is the magnitude of the EMF in millivolts : An astronaut who is repairing the outside of her spaceship accidently pushes away a 98.9-cm-long steel rod, which flies off at 10.5 m/s, never to be seen again. As it happens, the rod is oriented perpendicularly to the magnetic field in that region o.. |
