Question

What is angular velocity of an oscillating pendulum of length 150cm?

Answer 1

`"2.6 rad/s"^2`

Explanation:

Assuming the pendulum is simple then,

Angular velocity`= sqrt(g/l) = sqrt(("9.8 m/s"^2)/(150 cancel"cm" × (10^-2 "m")/cancel"cm")) = "2.6 rad/s"^2`

Is there any difference between angular velocity and angular frequency?
