Question

A rotating disc has a knob on the edge of it. The disk completes a rotation every 3 s. Using this information, you can calculate the angular __________ of the knob

Answer 1

The angular velocity of the knob on the rotating disk that completes a rotation every 3 seconds is approximately 2.09 rad/s.

Step-by-step explanation:

The angular velocity of the knob on a rotating disk that completes a rotation every 3 seconds can be calculated. Angular velocity is defined as the change in angle per unit time, which means it is how fast the angle changes as the object rotates. To find the angular velocity, we use the formula ω = Δθ / Δt. Since one complete rotation equals 2π radians and the disk completes this rotation in 3 seconds, we can calculate:

ω = 2π rad / 3 s

ω = (approximately) 2.09 rad/s

Therefore, the angular velocity of the knob on the edge of the rotating disk is approximately 2.09 radians per second.
