A mass on a spring nearly hits the ground 20 times a minute, its frequency is
- 3 cycles per second.
- 1/3 cycle per second.
- 20 cycles per second.
Explanation from PART66Online
Frequency is the number of complete cycles per second. The mass completes 20 cycles in 60 seconds, so f = 20 / 60 = 1/3 cycle per second (Hz). Stating 20 cycles per second confuses the per-minute count with a per-second rate.

60 / 20 = 3, so one hit takes 3 seconds.
So in 1 second it will do 1/3 cycle.
So in 1 second it will do 1/3 cycle.
