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 = 51 minutes left in class. Feedback: 0% deduction per feedback. 14% Part (c) Through what angle (in radians) will the hour hand sweep before the end of class?

While sitting in physics class one day, you begin to ponder the workings of the analog clock on the classroom wall.

The Lost Drone. You and your team are exploring the edge of an Antarctic mountain range and you send a drone ahead to help navigate. After takeoff you lose sight of the drone and, a few seconds later, the controls malfunction and the drone stops sending visual images and navigational information except for speed and directional data. Changing speeds erratically, the drone heads west until it makes a drastic turn at the 5-minute mark to B = 30° east of south. After nearly ten minutes, the speed drops to zero and the drone stops sending data. It has crashed. Using the speed/directional data, the team draws up the graph shown below. (a) How far is the drone from you? (b) In what direction must you go to retrieve it? Express your result as a geographical direction west of south. 20 (s/w) / Velocity 15 10 LO 5 0 0 WEST 100 200 300 Time t (s) 3° East of South 400 500 600

Case 1: A DJ starts up her phonograph player. The turntable accelerates uniformly from rest, and takes t1 = 10.7 seconds to get up to its full speed of f1 = 78 revolutions per minute.Case 2: The DJ then changes the speed of the turntable from f1 = 78 to f2 = 120 revolutions per minute. She notices that the turntable rotates exactly n2= 16 times while accelerating uniformly. a)How many revolutions does the turntable make while accelerating in Case 1? b)Calculate the magnitude of the angular acceleration of the turntable in Case 1, in radians/second2. c)How long (in seconds) does it take for the turntable to go from f1 = 78 to f2 = 120 RPM?
