Easy -1.8 This is a direct one-step application of the formula ω = v/r with simple numbers (8/20 = 0.4). It's a 1-mark multiple-choice question requiring only recall of a basic circular motion formula with no problem-solving, making it significantly easier than average A-level questions.
A cyclist travels around a circular track of radius 20 m at a constant speed of \(8 \text{ m s}^{-1}\)
Find the angular speed of the cyclist in radians per second.
Circle your answer.
\(0.2 \text{ rad s}^{-1}\) \quad\quad \(0.4 \text{ rad s}^{-1}\) \quad\quad \(2.5 \text{ rad s}^{-1}\) \quad\quad \(3.2 \text{ rad s}^{-1}\)
