1. A man walking on a tightrope carries a long a pole which has heavy items attached to the two ends. If he were to walk the tight-rope with just a pole, what difference would it make to his balance? Discuss this in terms of angular rotation, angular momentum, and moment of inertia.
All discussions should include an in depth analysis and references.
2. Discuss the applications of rotational forces in real-life situations. Remember to include relevant equations.
3. Discuss stress and strain of materials in terms of Hooke's law.
In order for a car to turn along a curve in the road, it must experience a centripetal acceleration (according to an inertial observer). what force is responsible for providing this acceleration
A boat is traveling where there is a current of 0.20 m/s east. To avoid some offshore rocks, the boat must clear a buoy that is NNE (22.5) and 3.4km away. at what angle relative north should the boat head
A flight attendant pulls her 63N flight bag a distance of 308m along a level airport floor at a constant velocity. The force she exerts is 45N at an angle of 57° above horizontal. Find the work she does on flight bag.
Particles pass through a single slit of width 2.3 mm. The de Broglie wavelength of each particle is 515 nm. After the particles pass during the slit, they spread out over a range of angles.
