Question on: JAMB Physics - 2017
What is the speed of a body vibrating at 50 cyclic per second
A
100 πrads\(_{−1}\)
B
200 πrads\(_{−1}\)
C
50 πrads\(_{−1}\)
D
400 πrads\(_{−1}\)
Ask EduPadi AI for a detailed answer
Correct Option: A
1 cycle = 3600 = 2π rad
∴ 50 cycle = 2 π rad × 50 = 100 πrad
∴ = angular speed = 50 cycles per seconds = 100 π rads(_{−1})
