Neco 2023 Physics Question 32
Practice objective / multiple choice question 32 from the 2023 Neco Physics examination.
A speed‑time graph for a car is piecewise linear: from \(t=0\) to \(4\ \text{s}\) speed rises uniformly from \(0\) to \(12\ \text{m s^{-1}}\); from \(4\) to \(7\ \text{s}\) speed remains constant at \(12\ \text{m s^{-1}}\); from \(7\) to \(10\ \text{s}\) speed falls uniformly to \(6\ \text{m s^{-1}}\). A student measures the total distance travelled with a wheel‑counter and records \(84\ \text{m}\). Is the student's measurement within \(5\%\) of the true distance obtained from the graph? Answer "Yes" or "No".
