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 . 1. (3 points) Consider the system of coupled wheels shown in the figure at right. The radius of wheel A is one half of that of wheel C. If wheel C is rotating at a constant angular speed of 100 rev/min, and assuming the belt does not slip, which of the following statements is correct. a) The angular speed of A is half of the angular speed of C. b) The linear speed at the edge of wheel C is half of that at the edge of wheel A. c) The angular speed of A is varying with time. d) The acceleration felt on both wheels is zero. e)
