While sitting in physics class one day, you begin to ponder the workings of the analog clock on the classroom wall. You notice as the hands sweep in a continuous motion that there are exactly t = 44 minutes left in class. 10 Randomized Variables t= 44 minutes .8 Part (a) Through what angle (in radians) will the second hand turn before the end of class? Part (b) Through what angle (in radians) will the minute hand sweep before the end of class? Part (c) Through what angle (in radians) will the hour hand sweep before the end of class? Part (d) Calculate the angular velocity of the second hand in radians per second. Part (e) Calculate the angular velocity of the minute hand in radians per second. Part (f) Calculate the angular velocity of the hour hand in radians per second. Part (g) Is the angular acceleration of the second, minute, and hour hands the same? Pick the most accurate response. O No. The minute hand has the largest angular acceleration O Yes. Each hand has the same non-zero angular acceleration. O No. The hour hand has the largest angular acceleration. O Need to know the length of each hand is to answer. O No. The second hand has the largest angular acceleration. O Yes. The angular acceleration of each hand is zero. 31
