Problem 1: A disk at rest experiences a constant angular acceleration for t= 55 s, at the end of which it is spinning with a frequency of f= 85 rpm. Please answer the following questions. Part (a) Write an expression for the magnitude of the angular velocity of the disk after the acceleration in terms of the frequency. Expression: Select from the variables below to write your expression. Note that all variables may not be required. a, B, o, 00, T, 0, d, f, g, h, j, k, m, P, t Part (b) Calculate the magnitude of the angular velocity of the disk in rad/s at time t = 55 s. Numeric : A numeric value is expected and not an expression. Part (c) Write an expression for the average angular acceleration of the disk agve in terms of angular velocity. Expression : dave = Select from the variables below to write your expression. Note that all variables may not be required. а, В, о, од, п, ө, d, f, g, h, j, k, m, P, t Part (d) Calculate the magnitude of the average angular acceleration of the disk agve from rest to t = 55 s in rad/s2. Numeric : A numeric value is expected and not an expression. dave Part (e) Write an expression for the period T of the disk in terms of frequency f. Expression : T = Select from the variables below to write your expression. Note that all variables may not be required. O, B, o, 00, T, 0, d, f, g, h, j, k, m, P, t Part (f) Calculate the magnitude of the period of the disk T at time t = 55 s in seconds. Numeric : A numeric value is expected and not an expression. T =
