The pendulum on a grandfather clock swings from side to side once every second. if the length of the pendulum is 3 feet and the angle through which it swings is 10 degrees, how far does the tip of the pendulum travel in 1 second?

We need to find the distance the tip of the pendulum travels in one second.

The tip of the pendulum travels 0.52 feet in 1 second.

The length of the pendulum is 3 feet which is the radius (r).

The angle of the swing is which is .

The time given is 1 second.

The distance the tip of the pendulum will travel in one second will be the arc length of the sector of the circle.

The formula to find arc length is

The tip of the pendulum travels 0.52 feet in 1 second.
