Variable Acceleration (Calculus Kinematics) | 30 Worked Examples | OCR B MEI A-Level Maths

30 fully worked questions on variable acceleration for OCR B (MEI) A-Level Maths (H640), built for Year 12 and Year 13 students who want to master calculus in kinematics. Every question is written in the style of the H640/01 Mechanics papers, with command words such as Find, Determine and Show that, and one question carries the detailed reasoning instruction. The pack covers v = dx/dt and a = dv/dt, integrating with initial conditions, instantaneous rest, greatest and least velocity, displacement and average velocity, two particles meeting, and the signature hard skill: distance travelled across a change of direction. You also practise spotting when suvat is valid, which is only when acceleration is constant. Every solution is broken into single steps with a plain-English reason, an arrow note on every line and OCR style M1, A1 and B1 marks placed exactly where a mark scheme rewards them, so students see how marks are earned and where they are lost. Questions run from entry level to multi-step exam style and the total is 172 marks. Ideal for homework, revision, tutoring or self study, and a complete answer for every question is included.

What’s inside:
Easy: 10 questions on differentiating and integrating polynomial motion, rest, displacement and average velocity
Medium: 13 questions on distance travelled, meeting particles, unknown constants and modelling
Hard: 7 questions on multi-stage distance, two-particle problems and exam-style reasoning
