For a right-moving centre and clockwise rotation on stationary ground, contact-point velocity is v − ωR. With R = 0.20 m and v = 3 m/s, omega = 10 rad/s gives +1 m/s, sliding right; omega = 15 rad/s gives zero, instantaneous no slip. Continued no slip requires the constraint to remain satisfied.

Compare the actual 2026 Advanced and Main syllabus documents. Advanced explicitly lists rolling without slipping and excludes R/S and E/Z configurations in its cited stereochemistry scope. Main requires its own subtopic check; shared headings do not prove identical scope. The comparison does not confirm a 2027 syllabus.

An ideal uniform solid cylinder rolls from rest without slipping or energy loss: combine mgh = ½mv² + ½Iω², I = ½mR² and v = ωR to get v = √(4gh/3). With h = 0.60 m and g = 10 m/s², v is approximately 2.83 m/s.

For N₂ + 3H₂ → 2NH₃, start with 2 mol N₂ and 3 mol H₂. Moles divided by coefficient gives 2 for nitrogen and 1 for hydrogen, so H₂ limits the ideal complete reaction. It forms 2 mol NH₃ and leaves 1 mol N₂.

For the original example I equals the integral from zero to pi of x sin x dx, substitute x = pi minus t. Add the reflected expression to get 2I = pi times the integral of sin x from zero to pi = 2pi. Therefore I = pi. The method uses the stated interval and sine symmetry.
