Neco Model Questions Vol1 2020 Mathematics Question 45
Practice objective / multiple choice question 45 from the 2020 Neco Model Questions Vol1 Mathematics examination.
The time \(T\) (in seconds) taken for a particle to travel a distance \(s\) (in metres) under a constant acceleration \(a\) (in \(\text{m/s}^2\)) varies directly with \(\sqrt{s}\) and inversely with \(\sqrt{a}\). If it takes \(8\) s to travel \(20\) m when the acceleration is \(2\ \text{m/s}^2\), find the time required to travel \(45\) m when the acceleration is \(5\ \text{m/s}^2\). Give your answer in exact form and to two decimal places.
