Directions: Determine the magnitude and direction of the rotational quantities asked in the following problems. Show your soiution. 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. 3. What is the angular acceleration of the wheel of the bicycle travelling forward when it reaches 60 rpm in 2 s? Answer in radians/seconds?.
