Calculate the period of a ball tied to a string
of length 0.3 m making 1.9 revolutions every
second.

• physics -

The period is always 1 divided by the frequency.

In this case that is 1/1.9 seconds.

Actually, the period cannot be that short for a string that short, whatever the pendulum motion is.

do you have an answer though? I'd really appreciate it.
