A particle, moving in a straight line, decelerates uniformly, from a speed 5Ums−15U\text{ms}^{-1}5Ums−1, for 6 seconds which reduces its speed to 2Ums−12U\text{ms}^{-1}2Ums−1. It maintains this speed for a further 16 seconds before decelerating uniformly to rest in a further 2 seconds.
Sketch a velocity-time graph for this information.
Find an expression for each of the decelerations in terms of U.
Given the total distance is 220m, find the value of U.
Practise Edexcel AS Level Maths Constant Acceleration with exam-style questions for AS Level Maths. 17 questions covering Modelling Assumptions, Quantities and Units, Working with Vectors, Displacement-Time Graphs, Velocity-Time Graphs, Constant Acceleration Formulae 1, Constant Acceleration Formulae 2, and Vertical Motion Under Gravity, matched to the Edexcel AS Level Maths (8MA0) specification and written in Paper 1 and Paper 2 style. Every question includes a full worked solution and mark scheme, so you can see where marks are awarded rather than just whether you got the answer right.
