MATHEMATICS 1 GCE A level Mathematics (9AM0) – Paper 32 Mechanics QP COMPLETE SOLUTIONS 2020 Part Working or answer an examiner might expect to see Mark Notes (a) R = mg cos  = 4 5 mg ... M1 3.4 This mark is given for a method to resolve perpendicular to the plane A1 1.1b This mark is given for a correct expression for R (b) F = mg sin  M1 3.4 This mark is given for a method to resolve parallel to the plane A1 1.1b This mark is given for a correct expression for F F = R M1 2.1 This mark is given for a method to use F = R to solve for   = 3 4 A1 2.2a The mark is given for fully correct working leading to the given answer (c) The forces acting on Q will still balance as the m terms cancel B1 2.4 This mark is given for a correct explanation (d) Q slides down the plane with constant speed 0.5 m s− 1 B1 2.4 This mark is given for a correct description of the constant speed of Q There is no resultant force down the plane so there is no acceleration B1 2.4 This mark is given for a correct description of acceleration GCE A level Mathematics (9MA0) – Mechanics – October 2020 student-friendly mark scheme (Version 1.0) This document is intended for guidance only and may differ significantly from the final mark scheme published in December 2020. 2 This study source was downloaded by 100000826098469 from CourseHero.com on 11-18-2021 07:45:18 GMT -06:00 https://www.coursehero.com/file/94042424/9MA0-32-Mechanics-October-2020-mark-scheme-student-friendly-1docx/ This study resource was shared via CourseHero.co [Show More]
