Question

8.1 parts d & c, previous parts are answered

Problem 1: Case 1: A DJ starts up her phonograph player. The turntable accelerates uniformly from rest, and takes t, = 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 f, = 78 to f, = 120 revolutions per minute. She notices that the
turntable rotates exactly n2= 18 times while accelerating uniformly.
Randomized Variables
t, = 11.6 seconds
n2 = 18 times
Part (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.
