• 1, How long it takes the clock's pendulum to swing to and fro

The time it takes for the pendulum of a clock to swing one back and forthTime

1, first use the formula to calculate T, T=2π√ (L/g) =2×14√ (0.5/8) =28×0.2259=419 seconds it swings back and forth a ticking sound, that is, 419 seconds rang once. One minute =60 seconds, so in 1 minute the clock about the number of ticks: 60/T=60/419=4283≈42 times.

2, L is the length of the pendulum (now understood as the length of the cycloid), g is a constant. Let's figure out T, T=2π√ (L/g) =2×14√ (0.5/8) =
