Case 1: A DJ starts up her phonograph player. The turntable accelerates uniformly from rest, and takes t1 = 11.6 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= 13 times while accelerating uniformly. a. Calculate the angular speed described in Case 1, given as f1 = 78 revolutions per minute, in units of radians/second. b. How many revolutions does the turntable make while accelerating in Case 1? c. Calculate the magnitude of the angular acceleration of the turntable in Case 1, in radians/s^2. d. Calculate the magnitude of the angular acceleration of the turntable (in radians/s^2) while increasing to 120 RPM (Case 2). e. How long (in seconds) does it take for the turntable to go from f1 = 78 to f2 = 120 RPM?
