Please answer question 3 parts a-c Problem 3: Case 1: A DJ starts up her phonograph player. The turntable accelerates uniformly from rest, and takes t1 = 10.5seconds to get up to its full speed of fj = 78 revolutions per minute.Case 2: The DJ then changes the speed of the turntable from fj = 78 to f2 = 120 revolutions per minute. She notices that theturntable rotates exactly n2= 17 times while accelerating uniformly.Randomized Variablest1= 10.5 secondsn2 = 17 timesPart (a) Calculate the angular speed described in Case 1, given as fj = 78 revolutions per minute, into units of radians/second.Numeric : A numeric value is expected and not an expression.Part (b) How many revolutions does the turntable make while accelerating in Case 1?Numeric : A numeric value is expected and not an expression.Part (c) Calculate the magnitude of the angular acceleration of the turntable in Case 1, in radians/second2.Numeric : A numeric value is expected and not an expression.a1 =Part (d) Calculate the magnitude of the angular acceleration of the turntable (in radians/second-) while increasing to 120 RPM (Case 2).Numeric : A numeric value is expected and not an expression.a2 =Part (e) How long (in seconds) does it take for the turntable to go from fj = 78 to f2= 120 RPM?Numeric : A numeric value is expected and not an expression.t2
