###### Question:

Problems 1) and 2) refer to the following: A yo-yo spins at an almost constant angular speed of 151 rad/s for many seconds after it reaches the bottom end of its string. The yo-yo will rise when you give the string a very brief tug. Assume no slipping as the yo-yo climbs the string. The moment of inertia of the vo-vo about its own central spin axis is 1-1.10x10- kg·m 1) (5 points) Which value best represents the height to which the yo-yo will rise above its low point? A) 44 cmm B) 27 cm C) 85 cm D) 19 cm E) None of these. (5 points) The yo-yo can be modeled as two uniform disks (cylinders), each of unknown radius R, length L = 1.2 cm, and mass M = 0.14 kg, joined by short cylindrical rod of length l - 1.0 cm, radius r-0.25 cm, and mass m 0.010 kg. Which choice best represents the radius of each disk, R? 2) A) 3.5 cm B) 3.1 cnm C) 4.0 cnm D) 2.5 cnm E) 2.8 cm
