Edexcel Paper 2H — Higher (QWC)
The velocity v (m/s) of a particle at time t (s) is shown as a curve. A tangent drawn at t = 5 passes through (1, 4) and (9, 24).
(a) Find the acceleration at t = 5. State the units. (3 marks) (b) Explain why the answer using a tangent is more accurate than using the chord between t = 0 and t = 10. (2 marks, QWC)
