| Topic | Circular Motion 1 |
| Type | Angular speed conversion and basic circular motion quantities |
| Difficulty | Easy -1.2 This is a straightforward single-step conversion problem requiring only the formula v = rω and unit conversions (diameter to radius, rpm to rad/s). No problem-solving or conceptual insight needed—pure routine calculation well below average A-level difficulty. |
| Spec | 6.05a Angular velocity: definitions6.05b Circular motion: v=r*omega and a=v^2/r |
\begin{enumerate}
\item A circular flywheel of diameter 7 cm is rotating about the axis through its centre and perpendicular to its plane with constant angular speed 1000 revolutions per minute.
\end{enumerate}
Find, in $\mathrm { m } \mathrm { s } ^ { - 1 }$ to 3 significant figures, the speed of a point on the rim of the flywheel.\\
