--- B - a thin uniform rod (mass 3.9 kg, length 3.9 m) rotates freely about a horizontal axis A that is perpendicular to the rod and passes through a point at a distance d= 1.0 m from the end of the rod. The kinetic energy of the rod as it passes through the vertical position is 20 J. (a) What is the rotational inertia of the rod about axis A? (b) What is the (linear) speed of the end B of the rod as the rod passes through the vertical position? (c) At what angle o will the rod momentarily stop in its upward swing?

7. (II) Atwood's machine was an apparatus that allowed a direct verification of Newton's second law. It could also be used to measure g. Two equal blocks of mass M hang on either side of a pulley; see Fig. 5.56. A small square rider of mass m is placed on one block. When the block is released, it accelerates for a distance H till the rider is caught by a a ring that allows the block to pass. From then on the system moves at a constant speed which is measured by timing the fall through a distance D. Show that (2M + m)D 2mH12 where 1 is the time moved at constant speed. m2 M Hotez D M FIGURE 5.56 Problem 7

As you told me before, you always have a hard time remembering new words. So, I also want are some good ways with you. After I learn a new word in class, I don't spell it out again and ag remember it. First of all, I like to make small word cards. I write a new word on one side and th aning of it on the back side. Then I can study those words everywhere even when I just have a . For example, I enjoy reading through the cards when I am waiting for the school bus. I also arf the Internet to look for songs with the new words in it. Last week, we just learned the word ? And I found the song Treat Myself. It's an interesting and nice song. I often sing the song also learn other words from the song. hope these ways also work for you, and maybe we can study together next time. ☺ - remember 19 spell ## meaninge everywhere a bit 5
