Winter 2003 Last Name______________________________ Physics 175 Exam #3 First Name______________________________ ID # ___________________ Points for each question are indicated in parentheses. Show your work for solutions to questions that require calculations. Explain from where you start to solve the problem and show your math flowing from it for full credit. Surround your result in a box and don’t forget to include the units for your result. If you need more space to finish a question, write BPP (Back of the Previous Page) at the end of the space provided and then complete your work on the back of the previous page. For multiple choice questions, circle the letter which you believe to be correct (or best). In all problems, take the gravitational acceleration g = 10 m/s 2 . Problem 1 (15 points) A uniform rod (length = 2.4 m) of negligible mass has a 1.0-kg point mass attached to one end and a 2.0- kg point mass attached to the other end. The rod is mounted to rotate freely about a horizontal axis that is perpendicular to the rod and that passes through a point 1.0 m from the 2.0-kg mass. The rod is released from rest when it is horizontal. What is the angular velocity of the rod at the instant the 2.0-kg mass passes through its lowest point? P1
