A motorcyclist accelerates his bike over a period of 3 seconds, and the motorcycle wheel increases from 23 revolutions per minute to 34 revolutions per minute. What is the angular acceleration of the wheel?

Question

Quizplus · Accepted Answer

The formula for angular acceleration (α) is: α = Δω/Δt Where: Δω is the change in angular velocity (expressed in revolutions per second - rev/s) Δt is the change in time (expressed in seconds) Δω = ω₂ - ω₁ Δt = t₂ - t₁ Solve for angular acceleration: α = (34 rev/s - 23 rev/s) / 3 s α = 11 rev/s / 3 s α = 3.7 rev/s²
