The period of a pendulum is given by:
where L is the lenght of the pendulum and g is the acceleration of gravity.
We know that the repaired pendulum has a length of 114.63 cm, then its period is given by:
Therefore the repaired pendulum has a period of 2.149 seconds.
We know that a day has 86400 seconds, to determine how many swings the pendulum make in a day we divide the total amount of seconds in a day by the period of the clock, then we have:
Therefore the clocks swings 40200 times a day (rounded to three significant figrues)
