Gce Model Questions Vol1 2021 Mathematics Question 22
Practice objective / multiple choice question 22 from the 2021 Gce Model Questions Vol1 Mathematics examination.
The time \(t\) (seconds) taken for a particle to travel a distance \(s\) (metres) under constant acceleration \(a\) (m\,s\(^{-2}\)) varies directly with \(\sqrt{s}\) and inversely with \(\sqrt{a}\). The particle's final speed \(v\) (m\,s\(^{-1}\)) varies directly with \(\sqrt{as}\). When \(s = 200\) m and \(a = 4\) m s\(^{-2}\), the time is \(10\) s and the final speed is \(20\) m s\(^{-1}\). Find the time and final speed when \(s = 450\) m and \(a = 9\) m s\(^{-2}\).
