Projectiles | OCR A A-Level Maths | 40 Worked Examples (H240)

40 exam-style questions on Projectiles for OCR A A-Level Mathematics (H240, Paper 3 Mechanics), each with a fully worked, mark-scheme-annotated solution. The pack is calibrated to OCR’s own conventions: g = 9.8 m/s (per the exam rubric), the particle-under-gravity model, i-j vector notation as used in recent H240 papers, and OCR’s M/A/B/SC mark codes rather than another board’s. Questions ramp in difficulty from Easy (resolving the launch velocity into components, time to greatest height, greatest height, time of flight and range on level ground, horizontal projection from a height) through Standard (speed and direction at a given time, position vectors, projection from a cliff, deriving the trajectory equation, clearing a wall, two-angle range problems, reconstructing the launch from a velocity vector) to Challenging (OCR-style ‘show detailed reasoning’ trajectory proofs in U/V form, least-speed-to-clear-a-wall optimisation, the R = u^2 sin(2theta)/g and 45-degree maximum-range derivations, two points on a trajectory, and full synoptic cliff-and-wall problems). Every worked solution breaks the method into one atomic step per line, with a plain-English note on each line and the exam mark folded in only where the real mark scheme rewards it. Trajectory and free-fall diagrams are drawn inline where they aid the setup. Ideal for revision, homework, or in-class modelling of full-method solutions.
