Directions: Determine the magnitude and direction of the rotational quantities asked in the following problems. Show your solution. 1. As viewed from the north pole, the earth rotates about its axis counterclockwise once in approximately 24 hours. What is the angular displacement of the earth for 1 hour in radians, degrees, and revolutions? 2. What is the angular velocity of (a) the second hand, (b) the minute hand and (c) the hour hand of a smoothly running analog watch? Answer in radians per second and in rpm.
