Your grandfather clock’s pendulum has a length of 0.9930 m. If the clock loses 95.6 seconds per day, by how many millimeters should you adjust the length of the pendulum?

  • Physics -

    Period=2PI sqrt(l/g)

    with calculus..

    dPeriod/dl=2PI 1/(2sqrtl/g)

    dl=dperiod sqrt(l/g) *PI

    dperiod=95.6/24*3600 second per second

    change in length=sqrt(l/g)*PI*95.6/24*3600
    = sqrt(.9930/9.81)*PI*95.6/24*3600
    = I get = 0.00110594656 m
    check my math.
