Question

A clock has a pendulum 22 cm long. If it swings through an angle of 32 degrees, how far does the bottom of the bob travel in one swing?

Answer 1

Answer:

12.287 cm

Step-by-step explanation:

32 degrees = 32*(π/180)rad/degree = 0.5585 rad

The chord length that the bob sweeps equals to the product of chord angle and the swinging radius, aka pendulum length

= 0.5585 * 22 = 12.287 cm.

So the bob swings a distance of 12.287 cm at an angle of 32 degrees.
