A grandfather clock has a long pendulum with an adjustable mass that is responsible for the clock's ability to keep regular time. This pendulum is supposed to have a period of 1s. You discover that the pendulum executes 117 complete vibrations in 2.00min.
a) Calculate the percentage error in the time the clock records.
b) How many hours slow will the clock be after a year?
I got 2.5% for a and 219.075h for b, but I'm not sure if that's right. any help would be appreciated.
