Unformatted text preview: PHY 1321 and PHY 1331 Summer 2009 Professor: Dr. Selahattin Celebi ASSIGNMENT 3 Due date: JL 30, 2009 3:30 PM 5.10. A 9.00-kg hanging block is connected by a string over a pulley to a 5.00-kg block that is sliding on a flat table (Fig. P5.10). The string is light and does not stretch; the pulley is light and turns without friction. The coefficient of kinetic friction between the sliding block and the table is 0.200. Find the tension in the string. Figure P5.10 Figure P5.20 Figure P5.44 5.20 . A 4.00-kg object is attached to a vertical rod by two strings as shown in Figure P5.20. The object rotates in a horizontal circle at constant speed 6.00 m/s. Find the tension in (a) the upper string and (b) the lower string. 5. 44 . A 5.00-kg block is placed on top of a 10.0-kg block (Fig. P5.44). A horizontal force of 45.0 N A 5....
