?
Solution

To find the period (T) and frequency (f) when angular velocity (q) is given, we use the following formulas:
T = 2π / q f = 1 / T
Given q = 240 rad/s, we can substitute this into the formulas:
T = 2π / 240 ≈ 0.0262 s f = 1 / 0.0262 ≈ 38.17 Hz
To find out how many cycles occur in 27 s, we multiply the time by the frequency:
Number of cycles = 27 s * 38.17 Hz ≈ 1030 cycles
-
To find the angular velocity (q) when the number of cycles and time are given, we use the formula:
q = 2π * (number of cycles / time)
Given 56 000 cycles occur in 3.5 s, we can substitute these values into the formula:
q = 2π * (56 000 / 3.5) ≈ 100 530 rad/s
