Question

What is the angular velocity of a 6-foot pendulum that takes 3 seconds to complete an arc of 14.13 feet? Use 3.14 for p...

Answer 1

1.For a six foot pendulum what is the circumference?
Circumference = 2 pi r
2. So for 14.13 feet arc, how much of the circumference (fraction) is it? use arc/circumference
3. For Angle, the full circumference = 360 degrees = 2 pi , so using the fraction, what is the angle traveled? (in radians)
4. So now you have the angle traveled in 3 seconds, What is the angle traveled in 1 second?
5. Congratulations you have found angular velocity
